Their embassy in the Paris of Aedguerre‘s Embassy Row was in Room 217.

This is from the sign in the historic site that protects that room:

"Built with the aid of Urushiol workers attempting to protect what became known as the Paris Hot Springs, this gwome is one of the most culturally unusual of the Diasporal gwomes.  First of all, most people are fluent in both False Cognate and Parisian.  Second, the Urushiol influence, though muted after the Battle of the Platte, is very much present in the marriage rituals common to all denizens of Terrain."

Urushiol were culturally similar to the people of Uru Urush in the mountains of sMontana.
