I'm going for Ran this playthough, thou I'm not trying to be mean to Kaisar, just sort of...neutral. Definetly not trying to string him along. And yes, the unicorn was in the NWN modules. I played the first Demonheart, then kind of delved into what had already been created, and discovered the NWN modules.
Yeah, I felt betrayed as well. Can't take anything at face value, lol. As for who is poisoning who...Hrm, I sort of went back to a earlier save and picked the two other different choices at a certain point, just to see what would happen. While it does seem to shed a slightly more light on the mystery, in the end it just add more questions.
Lamb is doing such a stupendous job with this story. Each chapter left me gripping the edge of my seat as to what might come next.
Edit: After thinking it over in my sleep, I leaning towards Janiya the witch for the one poisioning people. She's the more logical suspect for that. She has mentioned that she knows alot about plants and herbs and can pick them without getting herself hurt. Though Elos did mention about the cursed liquid in the trees...
