Aliastra

Aliastra was a savagekin who revolted against an organization of Ogres known as the Ton'ma. Aliastra and several other Savagekin were captured by the Ton'ma before she organized the prisoners and defeated or killed most of their Ogre captors.

Speculation
Aliastra is most likely a Night Elf, considering that Aliastra is seen to be able to transform into a Nightsaber. Additionally, one of the few places where a majority of Savagekin could be captured is Ashenvale.
