Castlekeep Ruins

This is an old castle in Daventry surrounded by a moat. The Old Castle Keep of Daventry may be a much older castle ruins that even predates Edward's castle that Graham and Valanice lived in during King's Quest 1-7, later they moves into a castle on a mountain near the western sea. This is likely because Derek Karlaevaegen's placed Castle Daventry much father in-land nearer to the eastern great mountains on his map of the World of Daventry. The castle keep ruins has traps, a strange magical device, and a magical teleportation square hidden within its walls, and a hero of daventry from long agone is buried near its moat.

However, it may also be intended to be the same castle seen throughout the series up to KQ6 and likely existed all the way up to King's Quest 7 (Though the castle seen in KQ5 seemed larger than castle seen in previous games, perhaps due to renovation after the damage done by the three-headed dragon, and the Great Tear). If it is the same castle it has fallen into ruin by the time of KQ8, and King Graham and Valanice moved into a New Castle Daventry on a mountain in another part of the kingdom.
