Clava Thessara Infinitas is one of the closest guarded secrets of the Alterrans. A camoflauged station in deep space, this is the central hub for the stargate networks throughout Alterran territory. There is one of every color gate within or near the station. From this location, all the stargates within the Alterran galaxies can be monitored, they could also be controlled, activated, and deactivated by remote. Locations could be isolated, wormholes rerouted, and entire sections of the galaxy or galaxies quarantined if need be. As the hub for all six networks, it is arguably the most important Alterran installation of all time. It can only be accessed through its yellow gate, but can dial out through any of the gates.
