Tomes Daywalker started in the Star Wars: Galaxies universe and has since spread into multiple gaming universes, often as the founder, leader or participant in the Immortal Union.
Generally, the Immortal Union's purpose is to find and foster other Immortals, extending its reach into the gaming multiverse. Currently, incarnations have extended into the CoH/CoV, WoW, Eve, AA, CS, and CoD universes.
His goal is to live forever.
So far, so good.
