I referred to the Silver King in the opening post. 

Just to be brief. I plan to play the Red King. He is my primary. 

I wish for the Silver King to be a character who is hardly ever around or included. He and/or she (I haven't decided yet) 
for the most part will not be a combatant or really be around. I will play them as well unless I deem someone to be trustworthy and compromising and cooperative enough to play him/her.

There may be A colorless king. however, whethr he/she is like the one from the show is up to whoever plays them. Like i said this is a parallel world there are changes and what not such as characters and the like because I felt the anime series left at a point where it would be hard to play things as I/we wish without canon characters. And I'd prefer to leave the canon characters out. 

I plan to use the known kings. But honestly there really is only 1 unknown isn't there? Based on the wiki and the series there are 7 different ones right? Red, Blue, Silver, Gold, Green, Colorless. Those along make up 6. So if need be we could make up another couldn't we?

I hope this information is sufficient for now. It is kind of late and I need to sleep. If more information is needed I can get to you tomorrow either here or through Private Conversation. Pick your poison. lol
