Scaleback's Apartment

"I did not know there were centaurs in the the Basket. Where are you from, Sir Domhnall? Serrisil, of course, but which world?" She doesn't know all the different nations, states and governments that rule parts of each world on the Great Oak, but she knows the larger worlds attached to the world tree. Sir Domhnall probably doesn't come from one of them, though it'd likely be easier on Geneva if he did.

From the worlds of the Great Oak, it's unlikely they'll be further cross-overs into Nexus, in Scaleback's apartment or anywhere else for that matter; the tree is deliberately moving away. Does mean there's likely a time limit on how long the dwarfs and Jystereiel can get back safely, however.
