So I have a long time obsession with that particular series. I had attempted to make a sequel, but gave up. But I did come up with some backstory that would go with this kind of RP:
To save themselves, before the swords were fused, they created duplicates of themselves, and nobody knows where they are. Yet.
Josh discovered an ancient form of necromancy that brings someone back to their full former self. All Elders and Great Elders are resurrected.
Isis and Osiris somehow discovered this technology and used it to bring back all the Earthlords.
You can be any kind of creature from the series save Great Elders and older. Feel free to make up your own Elder, just don't make it too powerful and try to relate it to some myth...
So what do you say?
