The Co-GM would help to manage players, keep the plot moving along, deal with spammers and troublemakers, and if I should be gone for a while, take over. For my part, I'll manage players play a character, do my best to move the plot, deal with troublemakers, and play the dragon who is at the very least, the starting antagonist.
I'd like to begin as soon as possible, so once we have a co-GM and I post the dragon, I will start the IC.
Edit: I posted the dragon, a red beast named Arion.
