Like the sudden clap of thunder right as the storm starts; she appeared. Almost out of the sky herself. Her skin the most luminescent shade of white and her hair blowing around in the wind like lightning rods.
His skin shook with energy just thinking about her; reminiscing in her presence. He fed off it, almost to the point where he couldn't breathe without her. She was keeping him alive.
But that was the problem.
When you make someone so much to you, then you have next to nothing when they leave. And that's what happened to the poor timelord. He was left with nothing.
All alone in the oncoming storm.
