The new target planet chosen for Atlantis to land on after M12-578 was compromised when Dr. Weir was captured by the Asurans during the mission to steal a ZPM. Before Atlantis came this planet had no Stargate and was only accesable by ship. Little is known about this planet, apart from the fact it has five moons but only two can be seen. The planet itself is mainly a large ocean and the landmass is home to a species of giant venomous snakes. It also has a mutated version of a common childhood illness called Kiersan Fever that in this version of it causes a person to experience memory loss and get sicker and sicker until they die unless they are treated. On the mainland there is a common plant that grows on most Pegasus planets that also holds the cure for the disease located on the planet.
