Ylesian Space was a region of the galaxy on the border between the Mid Rim and the Outer Rim Territories, near the entrance to Wild Space. It encompassed the Si'Klaata Cluster, and bordered on the Tion Hegemony. Ylesian Space was named for the capital of the Ylesian Repubic, Ylesia. Ylesian Space was formerly Hutt Space, but its name was changed after the Vong conqured it. Differing accounts attributed different numbers of planets in Ylesian Space, but reasonable estimates range from a few hundred to a thousand inhabited worlds. The far end of Ylesian Space Space tapered into The Maw.
