The supposed 'mothership' of the Xanxost on Ibos. This spire of black steel first appeared during the Schism of Rampart and landed close to Tesera.
Not much is known about the Xan Obelisk, beyond the fact that Xanxost vessels go in and out of it on the daily. Silverbridge has supposedly made attempts to infiltrate the Xan Obelisk to seemingly no success as well.
