This is a Neverwinter Nights mod from a few years back. In a nutshell Hellfire with the NWN/DnD rules. It's pretty good so far, and really does highlight the differences between the two rulesets. Since 2/3rds of our variants were DnD based, it's interesting to see what really happens when you combine the two.
It's all there Griswold, Leo, Cain, and Gillian. Also, you can hire the orignal War, Rogue, Monk and Sorc. The Warrior is named Jarulf.
Characters:
Chela Lot Barbarian/Fighter Soloist,
Olia Lot Sorceress w Jarulf
