At this point, I'm still assessing interest, so I won't be giving anyone a claim on anything until I start the OC. After that it'll be first come first serve.

The only objects that have downsides are Gluttony and Pride, so how could we balance this? Would any enemies possess the artefacts? Possibly objects that are incarnations of the seven heavenly virtues: Chastity, Temperance, Charity, Diligence, Patience, Kindness and Humility?
[/quote]As for downsides, Pride actually doesn't really have a negative effect, simply a certain limitation. After all, I can't go making the objects too powerful, which is why Gluttony is the only one with a possibility of harming it's Avatar. I did that because the vortex is already extremely powerful and can be activated and controlled by the Avatar of Gluttony at will. Therefore, it's still rather difficult for Gluttony to kill it's Avatar, as it would basically have to be the case that the Avatar of Gluttony activates Gluttony while pointing it at himself.

Also, can one avatar be in possession of more than one item? So if Gluttony died to his own thing, can someone then pick it up and have two abilities?[/quote]

 I mentioned in Envy's description that it is the ONLY artifact which allows one to possess two of the Sin artifacts. There is no other way for someone who already has a Sin to claim another.
