Uldren Sov is Queen Mara Sov's brother and confidant, wielding substantial power in The Reef's matriarchy.[1]
Biography
He and the Queen help the Guardian find and activate a "key" to enter the Vex Black Garden, though he is reluctant to aid the Guardian in what he sees as a futile and suicidal task.[2]
At the onset of the Taken War, Mara Sov, the Queen of the Awoken organized a massive assault on Oryx's Dreadnaught. Its power proved too much for the Awoken armada, however, as it sent out a massive energy pulse, destroying most of the fleet. Uldren escaped alive and made it to Mars, while Mara is considered missing in action.
Personality
He often disagrees with the Queen, but she values his alternative perspectives. Conversely, he will comply with the Queen's decisions, even when they are against his will.[1]
