A journeying shape shifter happened upon a wolf and transformed him into a human, producing the first Quileute. These Quileutes may undergo what is called the “Wolf Imprint”.

Quiluete Tribe Legend
This imprinting is love at first sight, only much stronger as it creates a persistent and constant bonding between two people that can not be broken.

He will wait for the woman he loves by not aging, for he knows that she is the “One”.
This is a legend presented in the “Twilight Series”. Although there maybe no factual basis for this Tribal Legend, speaking from my own experiences I believe this to be true to some extent. At least for the animal side of humans as I can often identify with it, as “I still hunger”. But it is another thing when it is lost and can never be…
Older than I was and younger than I shall be. As I am I will always be.
I have a calling for my wolf for many years, but still have not found him.
