Hmm...
[] A dragon, to see what they think of dwarven mating rituals.
[] An assassin of Clan Eshin, to talk tradecraft and the best ways to assassinate a bride and groom.
[] One of the dwarves of Karak Dum, to see if they'll spill the beans on the whole Morghur situation.
[] A... giant toad, who is brimming with more magic than anybody you've ever heard of? Surely they'll have some useful insights for the Waystone project!
[] Your Avatar sense is tingling. See if any of the deities present have any advice for you in general.
