This original RP will have a dragon, his mate, his children, and some kobold servants, plus side-characters such as villagers the dragon extorts for tribute as well as would-be dragonslayers.

Whoever plays the dragon can name him, but I would prefer that three constants be adhered to: that the dragon be large and red, that he breathes fire, and that he is clearly in command of his territory, which is headquartered in a cave. I won't play the dragon or dragoness: I'd like to see how others handle them.

As for kobolds, those are small, dragon-like humanoids with snouts and tails, but no wings. They live in caves, work in mines, and they revere and serve dragons. 

The open roles so far are:

The Bull Dragon: Billobob
The Dragoness:
Dragon child(ren):
The lead kobold servant: Aristocles. 
Kobold servant(s):

Other characters can be suggested, even if it means giving the dragon multiple females as mates.
