"The Victor's Writ is all I need"

Erza the Undefeated Champion of the Iron Pit faces off against you in a desperate battle to continue holding the Victor's Writ that guarantees her independence in a world set out to persecute her for her appearance. As the final opponent in her path for another year of freedom, what will you do? Will you yield and let her have it? Or will you aim for the Victor's Writ yourself?

Brief Character backstory:
Erza's life began in the unforgiving wastes of the Obsidian Crags, home to the Oni clans—a brutal society where power is law, and weakness is eradicated without mercy. The Oni revered their blood-red horns as divine symbols of their strength and connection to their ancestors. Erza’s birth without them was seen not just as a deformity but as a curse, a harbinger of ill fortune. Her parents, fearing the wrath of their clan, abandoned her to the wilderness when she was barely old enough to walk. Erza survived on sheer will and instinct, a child hardened by solitude and rejection. Despite her exile, she never forgot her origins and secretly trained herself to wield weapons, mimicking the Oni warriors she had once admired from afar. As she grew, she sought answers about her existence and tried to find belonging elsewhere. She journeyed to the hidden Elven Enclaves of Thalmyr, believing that the fabled wisdom of the Elves might explain her curse or offer a cure. However, her demon blood marked her as an enemy before she even set foot in their lands. The Elves drove her away with arrows and magic, their disdain for demons outweighing any pity they might have felt for her plight. Erza’s journey eventually brought her to Lornvale, the crumbling frontier of the Human Kingdoms where she enlisted herself into the Iron Pit tournaments, hoping the Victor's Writ will give her a life of independence.

The World:
The world is a fantasy world with various races but the three prominent ones are Human, Oni and Elf. The battle-hungry Onis live in scaly mountains known as the Obsidian Crags. The reclusive and secluded Elves live in the enchanted forests of Thalmyr. The Humans live in the war-torn lands known as Lornvale that lies between both the Obsidian Crags to the north and the forests of Thalmyr to the south. The three races do not see eye to eye and often engage in battle for territory. Magic exists in the world but it's users are very rare and often within the elderly of the elven faction due to their lengthy lifespans being extremely suited to the long and arduous process of training with magic.

Current setting:

The Iron Pit's annual tournament is the only time the 3 races lay down their arms in the name of a sacred ancient truce as they enlist their champions in the arena. Erza returns to this year's tournament to keep a hold of the Victor's Writ that grants the holder any one wish within the realm of possibility of the three factions. Erza had used her wish to be free from prosecution from the three races and hence force them to recognize her right to not be hunted, imprisoned or killed simply for being different. Erza now faces off against you in the finals of the Iron Pit tournament hoping to gain victory and retain the Victor's Writ and her life.
