I recently decided to add a secondary tunnel in the lava tubes in Flood Season which leads to a small hold of a vampire Sor 4 who is affilliated with the Cagewrights, who was sent to keep an eye on the Ebon Triad and guard them from attack. I also took one of the wands from Triel and gave it to the vampire.
I want to know some of the other side quests and encounters people added to the AP.
