Odo's Fleet is visible in the Gavara Sector during “Home” as an entry point to Empersa. It is composed of Odo's Flagship, the C.U.V. Tain, the U.S.S. Defiant and related faction forces. The L.S.S. Reskava is visible in Odo's Fleet in sector space, however it is not present in the mission.
The Gavara sector is rather unremarkable in most aspects, save one - it has been a major staging area for Dominion fleets for over a hundred years.
