It's a topic that has been explored in the past, but with a twist. Normally the budding Sorceress attempts to take the plunge into the world of arcanic power by calling forth the power of an extra-planar creature to do her bidding and thus, things go terribly wrong. I'd like to do an RP where the young Sorceress (my character) attempts to conjure a Demon, but do to a twist of the wording it is not a Demon whom is summoned to her world, but SHE whom is summoned to the Demonic world of the Abyss. Now, she must find some way to flee this terrifying place of Chaos and Horror. Of course, she'll probably end up meeting many of the inhabitants of the Abyss.
I'm looking for someone who wouldn't mind playing the powerful and terrifying monsters of the Abyss (I'm thinking most would be very similar to D&D's rendition of Abyss dwellers). If you're interested in taking up the roles, send a PM my way and we'll discuss the idea further.
