Telluis

Battle Marshal Telluis the Victorious was a Sontaran, and a member of the of the Sixth Sontaran Elite Division. He was assigned oversee the construction of the massive warship known as "The Sontar".

Building The Sontar
Shortly after Field Major Styre failed to deliver his survey on the Human weaknesses, Sontaran High Command ordered Telluis to build an advanced space vessel that could aid the Sontaran Empire conquering Mutter's Spiral through brute force.

After completing it the ship, Telluis named the ship The Sontar after the home planet of the Sontaran race.

After unleashing his fleet upon the galaxy, Telluis witnessed the fall of several planets before focusing his fleet on GalSec, the Human race's main colony. After successfully forcing the planet to surrender, Telluis decided to test The Sontar's main cannon on GalSec.
