I dunno, I liked the Vanu quests. You were helping them build a new community and grow into the role of independent leadership. although mostly I just really wanted to be able to Haka

I've been doing the Kobold/Amaljaa/Sahagin quests for the Relic, and the Sahagin are probably my favourites of those, followed closely by the Amal'jaa. I'm completely in agreement with CyrilLucifer about the Kobolds though; while endearing (especially the Bomb Alchemist), I ultimately only had the most tenuous grasp of why I was bothering to help their lazy butts at all, and that resolution seems vaguely disappointing as well. Thank god for those Titan Cobaltpieces! But enough of them have been enjoyable enough, and I like the Gnath enough, that I'll probably be on board for this.
