Efreet

Lavok isn't a lich. From the story, it seems he wanted to live forever while remaining human so instead he developed some power to assimilate his family members and renew his body.

I understand everything about the "consequences" part (the unseeing eye should certainly be added) except for one thing. What exactly can go worse with Firrkragg? He has already conquered the area (he doesn't care much about the previous owner) , he has a tribe of orcs that serve him and no real interest in turning them into an army (which would be costly to keep) . The kid would probably die if not saved in time but if the party doesn't go there at all, what will happen?
