The Afterlife
Their are many heavens and many hells. So many afterlives await those that perish that it would be impossible to name them all. But one such afterlife is the Eternal Arena. The dead that enter this plane of existence become reanimated as their former bodies, what they would consider their "prime". While this Arena Attracts many dead fighters to it's plane, it also brings in spectators. (Should be of note that no one came here willingly) Spirits here can enter the Arena to fight other reanimated spirits, with the winner getting any one wish that the god of the realm would allow, the most popular being reborn or revived on earth.
Those that die in the Arena need not worry, as they will be reanimated near the entrance a few days later after being in an unconscience state from being dead. Losers are free to try again next season.
Spirits also get any weapons, even exclusive and/or magic items they had in life. The only way out of this arena hell is to win.
Those that can not fight take advantage of spectating the Arena and living in the undead city next to the Arena.
The Layout
The Arena resembles that of a traditional roman Arena, with black bricks and an assortment of decorations within. In the walls between the arena and the entrance are many floors and hallways with luxuries. There are food vendors, an armory, an infirmary to treat wounded spirits that haven't died, and other various buildings and shops. Money can be earned through gambling and winning matches.
Demons offer the services of these shops and rooms, servants of the god that owns this realm, they may also participate in the tournament to gain freedom as well.
Your character can be anything conceived of sci-fi or fantasy fiction, so long as it isn't to op which I'll be judging whether a character is overbalanced or underbalanced.
Earth is currently a slightly futuristic modern world with magic and the supernatural rare, though in the past magic, supernatural features and traditional fantasy races were common. Aliens from other worlds can also be allowed, overall these creations and backstories will have a sandbox on your part. You will be creating a lot of the world they were once alive in. You may also have characters from ancient timelines. Spirits need not be mortal, they just need to have been dead. Meaning that vampires and similar immortal creatures are authorized.
This will largely be an RP centered around PvP and social interactions entwined. Players do not have to be combatants, spectators can still socially engage with combatants in between matches. If you have any questions ask me. Do I have any interests?
