Regeneration

The TARDIS is screaming at him in his head as he steps inside. Gallifrey burns behind him. “I had to.”
The ship had defaulted back to the infinite white console room. Using up all it had just to stay alive.
The Doctor takes off his uniform and drops it into the shapeless space around the console.
He flips some switches and touches his face and his eyepatch. The holes and scars aren’t just physical.
The capsule dematerialises just as Gallifrey does. Gone forever before and after.
Tumbling through the Vortex, the ship screams silently on.
“Is it?” He looks at his hand, which is turning a pale white. “It’s Time, isn’t it?”
The Moment had broken him in every way but one. Until now. The final breaking point.
His hearts stop beating and he collapses. His bones break before they hit the floor.
The ship drops out of the Vortex and screams on as it hurdles towards a dead planet.
