Dragonriders (no Wingleaders/Weyrleaders/Weyrwomen/Etc unless its well discussed beforehand, as this should stay somewhat close to the way it is in the books. Those positions will be NPCed or played by people who have good knowledge of the story universe.)
Weyrfolk (Lots of room here)
Hold/Craft Folk (Even more room, but again, please no leaders unless its been discussed and you KNOW the universe)
Dragons (Odd part to play, but could be quite fun. Would be a novel experience to write/read about a mating flight from the dragons perspective...
this is mine
drake was a Harper till he was chosen by green canius so now he is one of the few Harper /dragon riders there are he plays a pipe instrument and his about 5'7" tall with long blond hair and is a hopeless romantic but still the lady's like him he has a blue fire lizard named wolf that's always close to him
