Info:  
Obsidian takes after her mother and is a very quiet individual. Though, when she plays the drums, she is the loudest pony around and really knows how to play her heart out. Dont be mistaken by her size. Rumor has it she once busted a giant boulder in half with one kick of the hoof. She doesnt take well to strangers and gives off a generally unwelcoming vibe. She will destroy anyone who dare tries to hurt her big sister, Permafrost.
