Rocnaw's story starts with her great grandfather, who was a half-orc name Ront Buckman (he gave himself the name "Bear Fist", or something around those lines, but that is another story). This explains Rocnaws deeper voice, despite being a beautiful lady.
Rocnaw was born in (and grew up in) Ireland. In her pre-teens, Rocnaw's family moved to America, where Rocnaw picked up some american slang. Just before coming to Hogwarts, Rocnaw's family moved back to Ireland.
Unfortunately, both of Rocnaw's parents passed away from natural causes, making Rocnaw the head of the Banslayer clan.
Rocnaw believes in being a free spirit, but still obeying the rules (most of the time *cough cough*). Rocnaw likes singing "war songs" (assuming the mods/admins aren't around *wink wink*).
