Tristas

Tristas is a young brass dragon, who we encountered in Kiris Dahn, while searching for the Slaying Stone.

She resides in the hot springs and is attended by the kobolds of the area. In fact, she had the Slaying Stone, and told us that she would give us the stone if we could prove capable of keeping it (she didn't want the goblins to get it, either).

Other info she gave us:

 * There is an ancient Blue guarding the Ogrepasses, who may be working with the Iron Circle
 * Tristas was waiting for her sisters before confronting him
 * She knew a Conrad (another Deva)
