Uldren Sov, the Forsaken Prince of the Awoken, and Lord of Crows. After the start of the Taken War, and subsequent disappearance of his sister, he vanished off the face of the universe.  There was no sign of him for many years, until his ship was found in the Hellas Basin of Mars. For years, he was imprisoned within the Prison of Elders, driven mad, and consumed by darkness. Seeing visions of his sister, the Awoken queen Mara Sov, he escaped with the aid of the Scorn Barons, stealing the Ace of Spades from Cayde-6, and killing him with it. He and his Barons then descended upon the Fallen refuge of the Tangled Shore, intent on escaping to the Awoken Watchtower on the horizon, and the gateway to a secret realm within. His intentions are unknown, but one thing is clear: After the events of the Last Call, he signed his own death warrant.
