Killed during transitional encounter. Party attempted to kill the cultists in the cavern so they could rescue Nolan, for his sweetheart Alyana and, more importantly, a sweet golden reward.
Turns out he was leading the cultists. Whoops. Bye bye Nolan.
Lord Nolan of Valmere. Son of Lady Illyria of Valmere. Mommy broke up his little romance and he found some new friends. Some cultist friends who taught him well.
