Tristan

Tristan is an angel, a field general in the ranks of heaven's army. He is feared among lesser demons for his effectiveness, although not well known among the higher ranks. Currently, there's a war between heaven and hell. There's been a truce for the leaders of heaven and hell to discuss terms. They've come together in a fortress built by traitors of the angel and demon army, completely neutral ground. You can be an angel, a demon, a human servant in the fortress, whatever.
