Morvannon

Morvannon was a female Dragon Rider and one of the last five remaining members of her race. Though she, like the rest of the Dragon Riders, originally served Zaros, Morvannon - along with Apropos - defected to Zamorak a week before the downfall of the Empty Lord. Despite her change in allegiance, after both Zaros and Zamorak vanished - the latter would eventually return as a god - Morvannon was branded a traitor by Zamorak's followers and was eventually hunted down and torn apart by helldogs.
