Highlander: Endgame2000

Methos:
You know a little about Buddhist monks. Some of them come to cherish life so much that to step on an insect or harm a blade of grass becomes a violation of their creed, so the place themsleves under an extreme form of protective custody, a sanctuary of sorts. Well, for an Immortal who comes to abhor the bloodshed, there's a similar solution - a way to be removed from the game forever. Though the price is unimaginably high, but you are, for all practical purposes, protected from the violence within you.
