The next dimension is nothing like Eden. Up is down and down is up. There are no locations but the ones created by the mind. You may only visit souls here and items which are purchased here oddly enough may be brought back to Eden. Also all training which you undertake her can be brought back with you if you return to Eden.

If you die in the Next Dimention you will be sent to Hell. If you
die in Hell you have to start all over. There's an evil side of
you in Hell, Everything about them is equal to you, but since
they're your evil half, all they're moves are a bit stronger than
your's, and they might have abilities that you have never heard
of. You can train with them. Once you are able to leave hell you
can challenge your evil self to a battle. If you win he will fuse
with you and double your power. Also you will get a special item
and u will learn the new move from your evil self. But if you
lose you have to start all over again.
