Ironically, this latest "I'll draw anyone as the Doctor" commission is probably gonna be the most controversial of the bunch, even though it's the most canonical. It's also really stretching the definition of "The Doctor", but I couldn't resist the challenge. And there's something gloriously transgressive about depicting him at all.
Gallifreyan legend speaks of three men instrumental to the creation of Time Lord society: the wily and sinister Rassilon; the brilliant but doomed Omega; and an "Other" lost to history. Some say this being is connected to the Doctor. Some even claim he IS the Doctor. But a lot of people believe a lot of different things about where the Doctor comes from, who he really is, and who he'll become. And always remember the first rule: The Doctor Lies.
A big special thanks to one of Doctor Who's great myth makers, Lance Parkin, for offering advice on how the Other should look (which interestingly, was very different from my initial idea). I did my best to mesh up the description he gave me with the fleeting bits of description Marc Platt offers in the novel "Lungbarrow". Hopefully this'll serve as a "definitive" version for this rarely-depicted character.
DOCTOR: A long time ago, on my home planet of Gallifrey, there lived a stellar engineer called Omega.
ACE: Stellar? As in stars? You mean he engineered stars?
ACE: Sorry. Go on.
DOCTOR: It was Omega who created the supernova that was the initial power source for Gallifreyan time travel experiments. He left behind him the basis on which Rassilon founded Time Lord society, and he left behind the Hand of Omega.
ACE: His hand? What good was that?
DOCTOR: No, no, not his hand literally. No, no, it's called that because Time Lords have an infinite capacity for pretension.
ACE: I've noticed that.
DOCTOR: The Hand of Omega is a mythical name for Omega's remote stellar manipulator, a device used to customise stars with. And didn't we have trouble with the prototype.
