SORA - The Dark-lab". Sora is the homeworld of the Nexus and its appearance follows the philosophy of its rulers to the letter. The planet is in essence one huge scientific hub. Super-modern cities blend together with natural surroundings and all of its resources are used to power the thousands of laboratories and testing sites.
The nature of Nexus is secretive and elusive so not much is known about planet surface and its populace, but their paranoia of outsiders led them to the take a more aggressive and militaristic stance.
