Archon

Smart, funny, condescending, very powerful. Archon is what is known as a world walker. World walkers can travel the multiverse with free will, and have immensely powerful abilities. He made a deal with a powerful being, he gave the being his name in return for immortality. Hence why he now goes by Archon. After thousands of years of traveling, he's finally come home. A lot has changed since he left, and he carries with him thousands of years worth of arcane/interstellar knowledge. Be careful.
