Terom

Terom is homeworld of the Tereno, an endangered member species of the Covenant fringe. A decade before the start of the Human-Covenant War, the native population and the planet itself was decimated by a reigning San'Shyuum Hierarch for a perceived slight on their part. It would later become home to the Terom Group, a secretive organization dedicated to changing the Covenant from the inside.

History
The homeworld of the Tereno, Terom held the species until the Forerunner-Flood War where they were taken and later reseeded after the firing of the Halo Array. After their reseeding by the Forerunners, the Tereno would through a series of global wars that nearly brought them to extinction more than once. During one of these wars, one Tereno faction began to develop advanced robotics and artificial intelligence for warfare instead of organic soldiers, which would lead to them gaining control over the planet.

Defences
As the true headquarters of the Terom Group and later the Forsaken, Terom has an extensive array of defences that have been methodically worked over. Before approaching the planet itself, one will come across weapon emplacements lodged across the debris fields that dot the solar system and several small hanger bays for drone craft to emerge from. The closest moon Skiamene possesses a military installation with ground-based hangers for strikecraft and plasma cannons.

If the Terom Group had yet to evacuate by the time the enemy fleet has advanced past the outer defences, the world is further protected by a defence fleet comprised of assorted heavy warships and corvettes. On the planet are multiple drone hangers capable of unleashing drone craft that can commit kamikaze runs against orbiting enemy ships if additional time is needed for evacuation.
