This is an RPG limited by only imagination.You can be whatever you want, do almost everything you want, and believe whatever you want.
The only few restrictions are:
No controlling other player's characters. There's an exception if they let you.
You cannot start out with mid-game armor,weapons,or stats.
No doing things too crazy(for example, having a god step down from above for inspection is not allowed)

Rules(things you have to do):
You have to have something leading up to a new character(for example:A portal appears.(describe the portal)A (explain what the character looks like)steps out of the portal.(you can do what I did for the example or you can introduce them in a different post))
You have to have starter stats at least like this:
HP:100
MP(for magic characters or multiple-class characters that have magic,aka optional):20
DEF:5
DEX:10
(weapon damage minimum is 1)
Damage without weaponry:1
End minimum list.
And that's pretty much it!
