Royal Guard #4 is a character in King's Quest Chapter IV: Snow Place Like Home.
Background[]
Number Three often gets mistaken for Royal Guard #4.
Number Four can be seen in the castle along with Royal Guards #1-3 when they asking Graham for commands and proclamations shortly before Graham was kidnapped by goblins. Though Number #4 does not speak.
Behind the scenes[]
Number 4 is not an official nickname in the game. however it is used as page name due to limits of the wiki not allowing “#” in page titles, it is a redirect command.
Assuming the unnamed guard with Numbers 1-3 is not Number Four, he could also be the one guards from Chapter One known simply as the Royal Knights.
