OS timeline

There are several alternative official timelines introduced throughout the series, due to placement of events varying between sources. Here are a few examples (none of these should be considered more or less authorative than any other version of the timeline).

Official Timelines

 * Companion timeline (timeline based primarily off of the dates mentioned in the companion)
 * Novel timeline (novel specific timeline)
 * KQ1 timeline (timeline and notes concerning references made in the KQ1 manual)
 * KQ2 timeline (timeline with variants based on the KQ2 manual)
 * KQ3 timeline (timeline and notes concerning references made in KQ3 and manual)
 * KQ4 Timeline (timeline that utilizes KQ4 manual dates plus variants)
 * KQ5 Timeline (timeline based off of the About KQ5 and KQ5 Hintbook.)
 * KQ6 timeline (timeline based off of KQ6 Game and KQ6/KQ7 Hintbooks)

Note there are a few inconsistencies between the various sources on the placement of certain events, so there is no single cohesive timeline. There are actually at severeral possible official timelines based on differences between the various sources.

These include variant references to time between the KQ Companion/KQ2 prologue story, KQ4 manual, and various references in official KQ hintbooks.

Each timeline is based off of references to periods of time between events, given in the official games, official books, official manuals, and official strategy guides. GC standing for Graham's Coronation. This dating system was chosen to represent the dating due to a couple of sources that based the amount of time that passed off anniversary of when King Graham became king. KQ2, KQ4, and KQ6 manuals/hintguides make reference to such anniversaries.

The first timeline is more of a list of dates from all sources (it includes all variant dates). The 2nd article is based primarily off of the internal dates in the King's Quest Companion (with additional dates from other sources). The 3rd, KQ4 Timeline, utilizes dates from the KQ4 manual (and includes dates from other sources). The 4th is based primarily on approximate dates given in the KQ novel trilogy (with dates from other sources).

In each timeline article, contradictory material is discussed briefly.

There are inconsistences between various sources, for example; The introductory story in KQ2 manual and King's Quest Companion implies that the events of KQ2 took place one year after KQ1 according to the KQ4 manual he saw Valanice in the magic mirror and left on the adventure three years after KQ1, the KQV Hintbook placed the events of KQ2 several years after KQ1 (implying it was more than two or three years). Each of these differences create three separate timelines essentially.

The KQV Hintbook has other discrepencies. According to KQ4 the royal twins were born two years after KQ2 (about 5 years after KQ1). In the king's quest companion the twins were born 5 years after KQ1, or four years after KQ2 (5 GC). The age of twins given in later sources in relation to dates given in those sources (KQ6 Hintbook, King's Quest Companion, KQ7, etc) support the birth of 5 years after KQ1 (although KQ2 is placed at different points in time). The KQV hintbook states that the birth of the twins was one year after the events of KQ2, several years after KQ1 (which doesn't fit with other references).

King's Quest Companion states that Alexander was kidnapped by shores of Lake Maylie during a summer picnic. The KQV Hintbook places the kidnapping in the castle nursery. KQV Hintbook also contains a possible discrepency for when Alexander was kidnapped by Manannan. It states that he was kidnapped exactly six months after his birth. However creates problems with other known details in relation to other sources; Alexander's was a few days or weeks from his eighteenth birthday, the story took place during late summer, and that See No Weevil places the twins birthdays in early autumn. If Alexander was born during early Autumnn, as per See No Weevil and supported by KQ3, and kidnapped during the summer (according to King's Quest Companion), then it would imply that Alexander could have been kidnapped up to nine months after his birth. King's Quest Hintbook's six month date (from autumn birthdate) would place his kidnapping in during late winter, early spring. The KQV Hintbook also places the events of KQ1 during the spring, but it is unclear what affects, if any, that would have on the timeline.

Fan timelines are inconsistent with the official timeline, and dates are off by a couple years.

King's Quest Timeline
The timeline below is a list of all dates made in official sources, including inconsistent dates. Note, it will be a bit confusing, as the same event may be listed more than once. To simplify things several of the 'main variants' will be shown with color coding, to help show where things diverge.

 * Sierra releases a new and graphically improved King's Quest I. It contained "creative license" that changed elements of the game world, that did not reflect the "real world of Daventry". It was a second "game reality".

Alternative dates/Discrepencies

 * According to the King's Quest Companion, the king's quest games take place over the course of 20 or 25 years.
 * The date of the first withdrawal is unclear. According to information in the Companion it apparently took place after the Ancient Ones had already become legend. According to the guidebook the last date the Ancient Ones had lived in Green Isles was about 1000 years before KQ6. This would mean the first withdrawal would have had to have taken place between 1000 BGC and 0 BGC. This has other issues with other information that suggests that Daventry was founded several millenia before KQ1 (which would suggest that withdrawal occured more than 1000 years before KQ1).
 * Depending on the source Daventry was founded less than 1000 BGC (after the Ancients became legend) or over 2,000 years before KQ1.
 * The introductory story in KQ2 manual originally implied that events of KQ2 took place one year after KQ1 (from the moment he saw Edward in the mirror). The novelization for KQ2 in the King's Quest Companion also states that KQ2 takes place one year after KQ1, mentioning that the Sorcerer had turned him to stone the year before. . The KQ4 manual, places of events of KQ2; three years after KQ1. The KQV Hintbook placed the events of KQ2 several years after KQ1 (implying it was more than two or three years).
 * According to the KQV hintbook and an article in InterAction Magazine (Fall 1992) states that the twins were born 1 year after events of KQ2. According to KQ4 manual, the royal twins were born two years after KQ2. In the King's Quest Companion the twins were born about four years after KQ2.
 * King's Quest: The Floating Castle, King's Quest V Hintbook, and an article in InterAction Magazine (Fall 1992) states that Alexander was 18 years old when he returned from Llewdor (or that 18 years had passed since Alexander was kidnapped). However, according to KQ3 (and several other sources) he and his sister were 17 when he returned from Llewdor.
 * According to information in KQ3, the game took place during the summer. However, a reference in King's Quest Companion which states that Pan plays a "Maytime dance" could imply that KQ4 takes place during spring. However, KQ4 begins directly at the end of KQ3.
 * The KQV hintbook and the article in InterAction Magazine (Fall 1992) states that Alexander was kidnapped exactly six months after his birth.The KQC suggests he was kidnapped one year after his birth (Alexander was held captive for seventeen long years). The six month dates creates problems with other known details in relation to other sources; Alexander's was a few weeks from his eighteenth birthday, the story took place during late summer, and that See No Weevil places the twins birthdays in early autumn (as supported by KQ3, and KQC). If Alexander was born during early Autumnn, as per See No Weevil and supported by KQ3/KQC, and kidnapped from the shores of Lake Maylie during the summer (according to King's Quest Companion), then it would mean that Alexander would have had to have been kidnapped over ten months after his birthdate . The King's Quest Hintbook's six month reference (from autumn birthdate) would place his kidnapping during late winter, early spring. The companion also states that Alexander was held 17 long years, suggesting he was kidnapped almost a year after his birth (or the following summer after his birth).
 * KQ5 takes place almost a year after KQ4 (23 GC) according to the KQV & KQ8 manuals, during following spring (24 GC). References within KQ6 states that Cassima was "locked in a room nearly six months" which implies it was six months after her rescue in KQ5. This would place KQ6 at about 24 years after KQ1. However the official King's Quest VI Hintbook by Lorelei Shannon places KQ6 at 25 GC, the same year as KQ7 ("...20th birthday...") which would be almost a year after KQ5. KQ6/7 taking place 25 years after KQ1 is supported in the King's Quest Companion). King's Quest Companion states that KQ6 takes place almost a year after KQV, and that Cassima was to be in seclusion for a year.
 * The exact timeframe for King's Quest: The Floating Castle is unclear. There are few locations that it could fit in relationship to details given within the book. The last major event mentioned early in the book is Alexander's escape from Manannan (and it is implied that he is at least eighteen). It also mentions that Alexander met the wizard Morowyn nine months before events of the book, he also appears to show no signs of depression (implying he has not yet met Cassima), the epilogue takes place in the following summer. This would mean that details given would place most of the book between KQ4 and KQ5. The epilogue would most likely have to take place after KQV.
 * The date that the magic mirror was obtained is implied to be over 500 years in KQ1 manual, and over 200 years in King's Quest: The Floating Castle.
 * At the end of the KQ1 remake its mentioned that an unspecific number of years of prosperity occurs following events of KQ1.
 * In an article by Peter Spear in Interaction Winter 1992, King's Quest - A Landmark Game, he claimed that the game "Picks up about three months after King's Quest V ended". It is actually said to aboue six months in the game. The article was original published in questbusters magazine, and was published before the release of KQ6. It discusses several other prototype ideas.
 * While the narrator in KQ4 calls him "old King Graham", Rosella states that Graham is still young. Several other sources claim that he was "old", as well.
 * According to an interview from Roberta Williams she stated; "Between III and VI, there’s only a period of about two years."
 * It is said in several sources that Alexander was several weeks from his eighteenth birthday when KQ3 began. Exact amount is not clear.

Misc. Notes

 * According to the narrator or Rosella, the mummy is about a 1000 years old. This is merely an appromixation and not necessarily accurate.
 * Derek Karlavaegen wrote in Guidebook to the Land of the Green Isles that the old castle had been around for over 300 years, before a newer one built around 100 years before replaced it.
 * In the King's Quest Companion Derek Karlavaegen says that it was nearly a year since the time he arrived on the shores of Isle of the Crown that he made it to Serenia. It is unclear which season he made it to the island (c. 7 GC).
 * Seven is the age of Rosella during Kingdom of Sorrow, which takes place in Spring of the following year (she had her birthday in autumn).
 * KQ6 and KQ7 official hint books says that Graham had just turned 19 at time of KQ1. Several references in KQ1 SCI imply that it is spring, but almost summer, "...spring flowers...", "...the hot summer months", "...before next winter..." The KQC, also mentions spring flowers (this is supported by a reference in the KQV Hint Book, although other dates given in the book are inconsistent).
 * The official novel, The Floating Castle, mentioned that Daventry's King's and Queens had been using the the Magic Mirror for more than "two centuries" until the day the Sorcerer took it from Edward. It should be noted that the date the Magic Mirror was stolen is not specific in the manuals or any other official source. We only know that it been stolen several years before King Graham was tasked with the quest of finding all treasures, and many years after the other 2 treasures had been stolen. King's Quest Companion implies that it had been stolen 20 years before. So the exact date would be around 220 years before Graham's Coronation, but could be as high as around C. 420 BGC.
 * How the 10,000 date relates to Daventry time is somewhat unclear, as time in Old Wood moves differently than outside the woods (or least has since the fairies moved in).
 * Reference to seventeen are made in KQ3 (Gwydion is nearing his eighteenth birthday). According to See No Weevil, Alexander and Rosella were born early autumn. Both Llewdor and Daventry are in the northern hemisphere above the 'tropics' (I.E. Kolyma) and share approximately the same seasons. They would turn 18 during 23 GC after Alexander freed himself from Manannan, and Rosella travelled to Tamir.
 * The day before KQ3, Alexander was busy 'cleaning' the floor in Manannan's room, and emptied the trash in the wizard's study

King's Quest Timeline Variations
No source ever gives specific calendar dates for when the stories took place, though the manuals mentioned how much time passed between each game. Even the official universe has two different theories on the existence of Daventry placing it in two different points in time or space. The manuals and KQ6 intro movie states that the games occured a long time ago in earth's past, for example, but the companion states that people withdrew from earth a long time ago to Daventry, and now Derek Karlavaegen is sending history of his world to earth.

With the release of King's Quest I (remake), an additional alternate version of the King's Quest 1 storyline was made, which included more dialogue. It also altered a few details in the game; including changes geography, item locations, and puzzle solutions. The collection of the three treasures of Daventry was more linear ending with the Magic Shield. One altered detail in the storyline for example was that serpent-like moat monsters had replaced the alligators that existed in earlier versions of the game. Though these changes were relatively minor, and the two games storylines remained relatively the same.

Additionally there was an official version of King's Quest 1 made for SMS, and an official version of KQ5 made for the NES, both had a few minor alterations from their respective games. The SMS King's Quest had new art for the people and places of Daventry, and interface similar to early Lucasarts adventure games, a few of the puzzles were altered in order to work with the interface, though the text of the story remained largely the same as the AGI original version of the game. KQ5 for the nes, had an interface similar PC disk version but the art design for the various locations was much different, and some places like the desert were reduced in size. Some of the dialogue was modified, location names changed, some of the cut scenes removed or shortened (for example Amanda and Austin never show up), and certain puzzles modified or changed. For example Dink will come from anywhere in the maze from the sound of the tamborine rather than than Graham having to find him in one of four rooms, and the maze is different than in the pc version. Additionally the sea monster at the edge of the sea is a tentacle rather than a loch ness type monster. However both adaptations stayed true to the original storylines.

The official King's Quest Companion chose to follow the original version of King's Quest I's story (rather than rewrite the novelization to incorporate the new material) as it was the most common version of the game released at least up to the 3rd edition of the book, and it would go against the conceit behind the story that they were actual documents coming from Daventry. The reference to this reasoning for not changing the story was removed from the introduction in the 4th edition likely due to the remake being more common than the original version by then. However the story was left unaltered for the same reason as the previous editions. King's Quest Companion referenced the alligators in the moat, whereas the novel, King's Quest: The Floating Castle, referenced directly from the remake (mentions serpents in the moat). Another difference is the order that the three treasures are discovered. In the original it could be any order, in the companion it is Mirror, Shield, Chest, and in the remake it is Mirror, Chest, Shield. However that difference is fairly minor.

The King's Quest Companion somewhat branched from the game's timelines in the 4th edition by implying that KQ7 was a fictional story within the King's Quest universe that contained more lies than truth. Though Derek admitted he didn't know for sure, and that the royal family may have chosen to keep the true events secret from him, or that some kind of great dreamer in his world was altering the face and history of his world.

In this timeline it is implied according to the King's Quest Companion that Rosella and Edgar would ultimately become the Heirs of Daventry implying a happy ending to the series as a whole.
