•Broadly speaking, I like the idea of including these pre-made encounter ideas with a bestiary entry. So, what follows is just nitpicking.
•In the mini-scenario about the innkeepers trial, it would be helpful to provide some clues for the PC's to find.
•The potion of summon rats is amazing. However, a recent unfortunate run-in with a bag of magic beans in my home game tells me that you also need to include a provision for what happens when a PC ingests the potion. I propose that the rats spawn in the stomach, crawl up the esophagus, and emerge from the mouth, dealing damage along the way.
•Did you mean for "Wisdom, goddess of Wisdom & War" to use a more unique name (maybe one that starts with an "a" and rhymes with "arena")? You could have just called her "the Goddess of Wisdom & War," or "the Goddess Wisdom" (as you do later on), if not.
