Orestes Wormhole
From StarFleet Bureau of Information
This wormhole, a short distance from Orestes Prime, leads directly into the Sagittarius Dwarf Elliptical Galaxy and Starbase Foothold, the Federation outpost that guards the other terminus, and into disputed Lehrren/Woren space.
It is through this wormhole that the new Agamemnon-class battlecruiser USS Odysseus was lost due to a freak d-warp accident.
