Theus-7 was a Titan who fought during the invasion of the Last City which marked the beginning of the Red War. During the initial engagement, Theus-7 helped defend a ruined structure full of civilians against the Cabal, from a balcony overlooking the scene. Before one of the soldiers of the Red Legion could execute a friendly Guardian who'd been injured, Theus swiftly drew his hand cannon and dispatched the would-be executioner before it could finish the Guardian and, in that same motion, stopped another Cabal soldier from terrorizing a group of children. This did not go without notice, and the Cabal forces promptly opened fire on his position.
Theus-7 reacted by attempting to activate his super ability, to no avail; It was at this point that the Traveler's Light had been severed from the Guardians with the activation of the deafening cage deployed by Dominus Ghaul. As a result, Theus-7, in spite of the stunning blow of having his Light siphoned, shouted for the crowd to run as he primed a grenade.
It is unlikely that he survived.
