Side note, the other form that Dervish turns into is, coincidentally, Lyssa.
The warden? She uses all five GW1 avatar forms during her fight, open world and in story.
As for the book area thing... I felt that heart was fitting.
Just because one has a bounty on them doesn't mean they are an ally. A person could've pissed in Joko's cereal and gotten a bounty placed on them, then use such information like a sunspear base to clear their name.
Reputation doesn't mean shit to some people, and they want proof. If you helped keep the histories slamming Joko, then they got dirt on you as well. These people have never met you, and depending on your choices in path of fire...
You think they'd openly welcome somebody who went and told amnoon to side with Joko against Balthazar? I don't think so. If you side with sunspears or remained independant yeah it's a little weird, but there is the chance the player had chosen joko.
As for Taimi, it made sense. Joko is all ego. What better way to torture and start getting back at the commander then making them watch their friend suffocate and die horribly? As for her golem, he had a massive amount of inquest to forcibly reprogram or tinker with it.
That inquest base after all, had been there for pretty much EIGHT years in the first city.
