If Sir Palamon (in Castle Daerion) ends his turn next to a master Broodwalker, is he defeated? I assume yes, since he is a " hero figure." Thanks.

He would be, as long as we're assuming that after he performs a move action that's the end of his turn. Since he's treated like a hero, the monster ability "Hive Defense" would apply to him.

Thanks!
