Firstly, I would like to point out that, if organized properly, this would be a fantastic thing. IC and OOC drama most definitely ought to be left at the door in such a case where this dream became reality. I'd also like to state that the whole 'dressing up like your favorite character' idea, while appealing to me, might not quite work out so well. As you may have surmised, Fowai here is my favorite character to play...
Fowai : Awww...you do care...
Fowai's Player: Hush, you.
But, while I might somehow manage to resemble him in one way or another, the more I think about it the more it doesn't look pretty. I'd have to dye my hair bright red, stain my skin jet black, and wear gold-eye contacts. I'm 6'3" and your average drow (despite Fowai's very un-average nature) comes to a height of about 5'. Also, I most definitely outweigh Fowai by at least a hundred pounds. So, if this ISRP Convention ever takes place and I have the funds and availability at the time to attend, I'll just use Imreis' idea and wear a name tag.
Fowai: That'd probably be best. You'd just look like some cheap knockoff of the original, and no one wants to see a bootleg copy of Fowai running around...
Fowai's Player: Why on Earth did I ever give you that sharp tongue of your's?
Fowai: The easier to skewer my foes? You know how much I like to stick my tongue out at my foes...
Fowai's Player: Whatever the reason, could you at least appear to hold some respect for your creator?
Fowai: Oh, but I do respect you, oh mighty Creator. I praise you for delivering me, your finest creation, to the world!
Fowai's Player: Deliver you to the world...more like unleash you on the world...
Fowai: Same difference.
