[Caution, "Day of the Doctor" spoilers ahead.]
Gallifrey is falling. The Daleks, looking victorious in the heat of battle with their legion of battle ready soldiers, the indestructible machines powered from inside poised to move in and destroy the Time Lords.
Two rebels emerge from the dust, bags packed and TARDIS' at the ready. Two Time Lords who had never met share the same idea- they're gonna get out and let the rest of their kind burn at the hands of the almighty Daleks.
The Rogue, a loner from the beginning, intends to head to Earth. The Renegade, not quite as sure of her final destination, also heads for the same place.
Then, the Doctor interferes. He saves Gallifrey, pocketing it in some alternate dimension, frozen in time, and lets the Daleks destroy each other in the crossfire.
Unfortunately, the reaction caused by his actions warps the two rebel's plans.
Their respective TARDIS liquefies and melds into their blood stream, making them something else, something more than Time Lord.
The Rogue, crash landing on a foreign beach on Earth, has become the Dimension Dragon as well- both a dragon and Time Lord shapes under her belt and the ability to transfer between the universes.
The Renegade, unsettling the ocean as she enters Earth, has become the Time Tigress too- the forms of a Time Lord and a tiger hers to control. Now, she can travel through time whenever she wishes.
Together, they'll hunt through the galaxies to find the one person who can help- the Doctor.
