Imagine, a high-level party searching frantically for an old, abandoned castle once held by a lord of King Arthur's level of fame and strength. But they arrive too late! The most powerful fortress in the entire world becomes an animated colossus and is run by disgraceful little creatures such as goblins or troglodytes!
I really like this creature and the potential of its "Movable Keep" ability. It's a good way to bring back old, low-level antagonists that the party may have forgotten about...
