After a life of devotion to Milani, goddess of devotion, hope, and uprisings and doing good works to help others better their life, Wennel is murdered and reanimates as a skeleton who now worships Urgathoa, and is killing all the people he helped in his previous life because those are the only names of people that he can remember and he is confused and thinks that they were responsible for murdering him.
This is awful and unbelievable.
Furthermore how does Remna animate as a crawling skeleton? And Wennel is hanging out with additional other undead that also somehow got animated - zombie shamblers.
The storyline would have been much more believable if Wennel was killed and animated by a necromancer of some sort who then commanded him to kill the people he had helped in his previous life.
This:
1) Gives a much more believable motive for the killings. The slavers want to discredit Wennel and create a distraction to remove attention from their activities. Just killing Wennel would draw attention to why he was killed and would more directly point toward them.
2) Doesn't rely on incongruous behavior for Wennel including a radical religion change.
3) Explains the other undead, including the freshly animated one.
4) Would provide plot hooks for additional stories if the DM wanted to continue with more adventures exploring the slavers or the necromancer.
The only obstacle to this explanation is that in PF2 Animate Dead is not on any spell list... yet.
This leaves Skeletons and Zombies as the only undead without a method for creation.
When you have a murder mystery adventure it is so much nicer if at the end there is some reasonable explanation for what happened, even if the adventurers don't put together all the clues. OR if you have a group who does put together subtle clues they aren't left with lame explanations that don't fit.
