The adventuring party here is made up of several interesting people. Kallum is a druid from the eastern woods, Mallory is an assassin of the Assassin's Guild in Beldarium, Conor is a barbarian form the now destroyed Worldcentre Mountain, and Urla is a paladin from the ranks of the holy warriors. The king of Andaria summoned you to go on a quest. The quest is to kill the demons attacking the kingdom. Be whatever. Magic exists, standard fantasy world. Good luck. (sorry for the bad image, I'm working on drawing a new background)

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.
