When Derek turned six he got his first permanent mark a small pinkish oval on his right hip. He'd noticed it right away posing as a stark contrast to the rest of his skin. Sure Derek had had lots injuries in the past, even now he had a long wound all the way down the left side of his back from getting into a fight with a wolf twice his age and size. But all of those had healed fading away to nothing.

He went to his mother to show her the mark. She considered it for a while. The fact that it hadn't faded told her two things. One Derek's soulmate was six years younger than him, for it was very clearly a birthmark. And two they were human, as wolves neither scarred nor received lasting birthmarks. The second gave them something to think about.

-Normally born werewolves would stay their whole lives unmarked being mated to another wolf. And even bitten wolves would lose all of their scars when changed leaving them with only their mate's marks. Unless, like in Derek's parent's case, the mate happened to be a werewolf too.-

This didn't mean anything though, werewolves didn't go looking for their mates, at least not until they were adults, and not even then if they were part of a secure pack. Although it wasn't because the wolves felt a pack supressed the need for a mate, but because the packs would go to meets giving packs a chance to meet other wolves outside their usual crowd. But this wouldn't work for Derek, not when his soulmate definitely wouldn't be there.


A/N

This first part is quite short and is mostly just introducing the universe, but what do you think of the idea? Do I need to give more information about the universe or elaborate on anything I've said? Feedback is greatly appreciated.

The next part will be about Derek after the fire and Stiles after his Mom's death.
