Finished reading the Astral Realms and the Underworld books. Astral would be pretty resource intensive, though a visit to Vau's Oneiros Deltaomega to dig up lost knowledge could be fun. The Underworld is probably more up to our character's powerlevels (assuming we have somebody with death 3) and would probably fit a search for the lost museum knowledge quest better. I have a general idea, I'll post something here so we can discuss it once it's a bit more defined.
