After AwesomeTree in the Dark started converting Drakon heroes for Descent I think we've ended up with a brother for Grisban and the beginnings of a brewer brothers backstory 🙂 :

I'm likely to stick with my suggestion of Gristtun the Merry as I feel having arrived at the name it works well, probably as a potion brewing type of healer.
So feel free to use either/both as your hero or an NPC or whatever, they are almost certain to pop up in the adventures I'm putting together.
