The ghost of the person we killed trying to return the favor by shooting us with an RPG? Yep, we are playing Exalted. At least its not an another giant mutant poodle trying to eat us. Though now that I think about it, that very short Abyssal snippet hinted the worriesome possibility of something similiar soon...
Anyway, what do we want to do? We are doing this little side-quest to gather information, so I personally would suggest actually capturing Viletta's ghost instead of just re-killing her immediately. As she seems to be in charge, she should be a good source for information, and with this many socially focused Exalts (plus demonic spiders to maybe threaten her with, which of she seem to be quite afraid for some reason), it shouldn't be too hard to pry that knowledge out of her.
