The Xenoresearch Labs are part of the floating Chozo city of Eastern SkyTown, Elysia. In Metroid Prime 3: Corruption, Samus Aran comes to this area as she seeks to destroy the Leviathan that has begun corrupting Elysia. She discovers that the Space Pirates have been using the facility to breed Phazon Metroids. These Metroids have not been contained well, it would seem, as several Pirate husks are encountered in the Labs. It is implied they were also working on creating more Parasite Queens, as corpses of large organisms similar to the creature Samus destroyed on the Frigate Orpheon can be seen in some rooms. One of them may in fact still be alive, as it can be seen moving slightly. The area itself shows advanced levels of decay and Phazon corruption, likely a result of the Pirate presence
