So we just finished the retaking of Fort Rannick in Hook Mountain Massacre. My group entered from behind the waterfall and secret passages, and came upon Lucrecia as soon as they entered through the basement. Kaven ran away while the group was distracted fighting Lucrecia, and they discovered his treachery, though they don't know exactly how far it goes.
They've since finished killing all the ogres and clearing the fort. Since there are no obvious clues to pursue as to the bad guys' plans, they're all assuming that hunting down Kaven is their top priority.
The book (anniversary edition) says that he'll try to rendevous with Lucrecia, but that's no longer an option. Where would he go at this point? Should I make it possible to track his movement once he left the fort, or would the heavy rain in the area wash away footprints?
The oracle of the group also took Divination as a known spell, so I'm assuming they'll find useful questions to ask and track him down one way or another. I'm just trying to figure out how that should play out.
