2. Zurn is –very- interested in maybe having a chance to study anything in the ancient city (maybe bring back a book or two). Particularly anything to do with the honoring of Moradin. So, convincing the Mants to get out of Dodge and into the ravine is of interest to him. Even the chance to study their culture and maybe write a few things about them would be fascinating for him. So, he would like to go back to the Mants and tell them of a bigger place that we, the party, know of. Hell, we could escort them there!
3. Zurn is well on his way to becoming a Master of Radiance (see Libris Mortis prestige classes) and subtle things will be happening to be a reflection of his affinity to that.
4. Zurn might seek out Lady Corynn to ask her if she knows anything about the changes (again, Master of Radiance) that are occurring with him.
