Ok so somebody help me out here. For the last week or so I've been trying to figure out exactly which of the NPC'S/book characters are died and which are not. What source book do I use for this info.
Ymir, in many cases, the time jump meant that the fates of most characters post 1385 DR has not been revealed or specifically specified, and WotC has kept the fates of many characters under wraps (the dreaded "NDA") so as to possibly use them later.
That said, I'd start with the 4e Forgotten Reams Campaign Guide, and search Candlekeep for further discussion on the topic.
One usually has far more to fear from the soft-spoken wizard with a blade and well-worn boots than from the boisterous one in the ivory tower. My Tabletop Writing CV.
Daviot is correct in pointing you to the FRCG, I'd recommend coming up with whatever fate you fancy for them, and if you have a specific character in mind I'm sure you'll get all sorts of good stuff on them here.
