Save The World? Nah I'm Good ¥ Time Walker

I'm Tempest Lethal and I am a Time Walker. No not a Time Lord, a TIME WALKER. We create universe's, there are an infinite amount of them. But many have fallen. I am the oldest Time Walker and this is the story of my first death.

(Sorry if you already did this but I thought of it years ago and it just hit me suddenly after watching doctor who.)
