The Mage is a completely average Time Lord, nothing compared to the Doctor, except that his TARDIS is a more advanced model. He was on vacation to Earth at the start of the Time War, and by the time he got to Gallifrey, the war was already Time-Locked. He broken-heartedly returned to Earth, and decided to try and protect it, unaware of the Doctor's survival. He chose to focus on Canada, but every so often he goes into the Time Vortex, and tries to pick up a TARDIS signal. He never has.
He's thin, with slightly spiky jet-black hair, stubble, hazel eyes, pale white skin, a black jacket over a green t-shirt, knee-length shorts, and black trainers. He's laid-back and casual, with a very long temper. He enjoys travelling, and figuring things out on his own, though he will ask for help if he needs it. He has a Type 65 TARDIS.
