Auriel is actually a Diablo character but she does have a Spirit Healer skin in Heroes of the Storm as a tribute to the Spirit Healers in Alterac Valley since it is a Warcraft themed Battleground/event they're doing at the moment.
I wouldn't consider the Spirit Healers a race since they're referred to as angelic beings who reside in the spirit world.
