Designation given to the planet where the Ori successfully created and activated the second Supergate in the Milky Way Galaxy. Like Kallana, this planet was most likely consumed by a black hole to form the event horizon for the Supergate.
SG-1, aboard the Odyssey, traveled to the Pegasus Galaxy equipped with an eighth-chevron dialing crystal and a Milky Way gate.

They then detonated directed warheads at the open wormhole, causing it to leap instead to the Supergate -- activating it and blocking the Ori from being able to dial in again.
