Somebody posted this in the forum of my site:
Sareena
"The Netherealm demon, Sareena, lost her human form in an attack from the fallen Elder God, Shinnok. She was transposed back into her demon form as her essence descended back to the 5th plane of the Netherealm. Sareena remained there until she discovered an abandoned portal that led to Outworld. Once in Outworld, she learned to feed off of the living aura of that realm to regain her human appearance. She no longer needed Quan Chis sorcery to sustain her exterior beauty.
While in Outworld, the demon known as Sareena encountered Sub-Zero. Since she had freed his brother from his confines of the Netherealm so many years ago, Sub-Zero offered her asylum within the Lin Kuei. His compassion may be honorable, but befriending a demon of Netherealm is not an action without risk... as Sub-Zero may soon discover."
I don't Know where he read it, or if it's even the true bio, but it's interesting to read it.
