The Faerie races of Earth have long since become disgusted with the alienation and discrimination forced upon them by both Heaven and Hell alike. Exiled from their original homeland when God's Angels siezed it to create Christianity's place called Hell, the Fae were pushed topside to live amongst God's newly created Humans. After centuries of struggling to survive against the ever-expanding Human population - with their poisonous iron and advanced reproduction rate - the Fae race is dying off. Desperate to survive and with farfetched dreams of someday reclaiming their original homeland, the Fae have turned to an unlikely group of allies: a small group of Earth-bound Angels. The groups - sharing a common cause - have united and formed an alliance with the goal of reclaiming the Faerie homeland, Gehenna. Their dream of someday retaking the acursed place is a distant hope at best... but for both the Angels and the many breeds of Fae that have united under the new alliance, the fight will be worth it - for if they succeed, the long-acursed Gehenna will finally become what it was at the begining: Eden - a timeless garden, free of the taints of the modern world's struggles of "good vs evil."
This is where our story starts. Members must choose either a Fae or an Angel character when creating their application. As a means of furthering the alliance and strengthening bonds, the founders of this revolution assign all new cadets together with a partner opposite them. These Angel-Fae partnerships are made in hopes of each learning to work with the other and to help smooth over age-old discriminations by forcing each of them to experience the other up-close-and-personal while working closely together.
Because of the nature of the RP, we will (eventually) also have select "special" characters open to senior Members and group Contributors. These characetrs include Heavenly Angels (angels that are still working under God and sent to oppose the revolution) as well as Hellspawn (demon/devil characters that are likewise sent to oppose the revolution.) Additionally, high-ranking, note-worthy characters (such as specific, notably powerful demons and angels) will eventually be introduced for play. Additionally, senior Members and Contributors may also be allowed to make a second "Earth-side" character after the storyline has progressed enough. These are mostly magically/spiritually inclined humans that choose to side with one of the three forces: Heaven, Hell or the Allied Rebellion.
