In the Forgotten Realms campaign setting, the city of Neverwinter was ruled by members of the Alagondar line starting with Nasher Alagondar up until the cataclysm.
I'm running a 4E campaign in Neverwinter, and one of my players' characters has the Neverwinter Noble theme. This theme makes him the last surviving heir of the Alagondar line, and the rightful ruler of Neverwinter.
We're going to have an adventure soon that will involve his backstory. I'm trying to figure out what, if any, canon information exists about his family. I've found some information on Nasher himself, but nothing on any of his descendants.
Do we know anything about this family, whether from Dungeons and Dragons publications, novels, games, or any other officially endorsed medium?
Assuming that this information exists, I think the best answer would include a couple key points, maybe a key family member, and references to the material that this information came from so I can conduct further research myself.
If this information is not out there, then an answer that somehow demonstrates this would be fine as well.
