Either you have to do some work for the tower’s master. That could be stuff like cleaning their orbs so they can ponder them later, preparing/finding magical critters to be used in their potions, putting away his stupid sentient magical artifacts that keep trying to escape or do some shenanigans… Whatever. And try to gather information/find escape routes etc. But imo if there is some knight gameplay, it should be a minor part of the experience, otherwise you will indeed feel like you’re just playing the knight
