Just to quote the 'Overview' in the OP:

"So this is an RP where 7 of you will play the roles of dead assasin spirits who can exist in the mortal world one at time through a single body, ([u]that changes in appearance with each spirit[/u]) while the others reside in the 'mind' of the single vessel; the limbo like 'penthouse'."

So yeah, we all change appearance depending on who is currently in control of the body :P
