Tyrael

Tyrael was a Nephilim in End War Online.

Background
Tyrael was a Nephilim who lived during the days of The First Void Insurrection. She was among the Nephilim who helped combat the Void Avatar. More notably, she helped bring down the corrupted Collosus known as Void Collosi, and she contributed in the efforts made to keep the Void Infectation contained.

During the aftermath of the First Void Insurrection, known as the Nephilim Purge, she was hunted down. After being cornered in Hell, she was confronted by the Demon King, Samael. The two fought a gruesome battle, but ultimately Tyrael stood victorious over Samael. Instead of putting Samael to the sword, she locked him away in a Void Prison in the deepest reaches of Hell.

Being mortally wounded herself, she spent the remainder of her life in Eden, where she eventually died. Her final resting place is still a mystery to this day.

Abilities
Tyrael was considered amongst her own kind to be one of the most powerful to walk the Worlds. Both a veteran practitioner of Soulcraft as well as a highly refined swordsman, she was deadly enough to easily flay a Void Collosus with a few precise strikes while keeping the Void within it supressed and contained.
