Cyril doesn't seek him out. He spends the morning having breakfast with Marikoth and taking care of Cassandra. Then he has to plan some troop movements and read correspondence as the Inquisition starts to bring more and more of their troops into Tevinter covertly.

When Vash seeks him out, he finds him in the only really nice house in the town. It probably belonged to a minor noble who once lived in the area. Now it's in a bit of disrepair, even after the Inquisition members repaired parts of it to make it a sort of HQ for the area.
