Move: 0 (Garrison)
Bogroll is, to all appearances, a simple follower. At his first appearance, he was about to become the (literal) target of a prank by one of the other henchmen. Wanda's desire to get "as far away from you as possible" when she encounters him holding a target-patterned parasol suggests that this is a recurring pattern.
After being promoted to lackey, he made a suit of armor for Parson and otherwise served him loyally. Parson, in contrast to the other characters, treated Bogroll with respect, something which may have influenced and inspired Bogroll's infatuation and fierce loyalty towards Parson.
