That's what I'm thinking, I mean, a full set of Knights would be nice, but it probably wouldn't happen. I do know I need to keep the Indigo Knight for Magni though, lol. Maybe the Gold Knight can go...
Six isn't a bad number though, and if I combine the roles of Thought and Memory into one character, then we have a nice group of seven. It shouldn't be too hard to arrange the RP so that not all Knights are needed.
I could even make it so that each Knight is actually the head of a small group, and the leader of the group is the one who earns the title of Knight. That way, should, say, the Crimson Knight leave the RP, instead of just a new Crimson Knight conveniently appearing, there would be an in-story explanation of "S/he died/was defeated and the next person from that pool of contenders was chosen".
Besides all that, I need to start asking myself questions in order to get basic plot worked out. You know, "Who are the antagonists?" "What is their goal?" "Why is this their goal?" "How are they going to accomplish their goal?" "What can the protagonists do to stop them?" "What are the consequences if the antagonists win?"
Then there's stuff like "What events will bring the Knights together?" "What are the Knights' weaknesses?" "What is a Nightmare's weakness?" "Are all Knights good?" "Are all Nightmares evil?" "Where will the characters get their power and abilities from?" "Will events in the real world affect them in the dream world?" "Can the dream world affect the real world?" "At what point does the Veil of Lucidity stop working?"
And then a week of shoving my outline in people's faces to see if they can poke holes in it.
