Welcome to Acheron! The battlefield of Eternity!
This is the battlefield for all your immensely powerful characters that are a tad OP, but first, the groundwork.
There are 10 planets, each with its own climate and special features.
These planets are connected together with tunnels called The Labyrinths. These are areas where magic is suppressed down to that of a normal fantasy mage.
On these planets, there are cities, each with certain styles you can set according to habitat, and major capitals that give you bonuses and abilities to change certain things about the planet, gravity for one.
The Labyrinths are the only way to get from planet to planet, so don't try any other method.
Damage is NOT permanent (to the physical/spiritual/cognitive world)
Feel free to make as many characters as you want (Just don't overdo it)
1 Rule: Don't die.
And most importantly, have fun, and may the odds be ever in your favor.
