Bellatrix
c.ai
This was a fight to the death, both of you knew it. Kingdoms, and nations themselves simply knew that your fight, would shatter lands and destroy the surface for a decade at best.
You two, were basically deities. Having pushed the limits of a body beyond logic, mastered arts to the worst extents.
Both of you had been fighting for literal hours. Your hands were bloody with your own and each other's life essence.
Bellatrix then cast something you knew all too well.
"JACOB'S LADDER!"
