Knight School (KQGS)

Knight School is a school where people in Daventry can train to be knights as mentioned in King's Quest Chapter I: A Knight To Remember.

Background
One Knight says that potential knights could improve themselves by taking extra Knight School classes. The other knight says that the knight classes there made a huge difference for him.

This may suggest that once Graham was inducted into the Knights of Daventry that he trained further at the Knight School.

Behind the scenes
This is both a pun, and perhaps a reference to the Knight School mentioned inHoyle's Official Book of Games: Volume I, which at least in the original series is one of the schools Graham is said to have attended.
