Arena of Ohnd in the Abyss

Hidden beneath the ruined legacy of the Broken Prince, the Arena of Ohnd is a place where vengeance and despair are bound in blood. Those who dare claim the cursed blade Vilus Incarnatus from the temple in J4 are torn across planes into this pit of torment.

Here, the revenant Kathvuz awaits, forever chained to the weapon he once wielded. His soul burns with relentless fury, his strikes infused with psionic screams that echo through the abyssal walls. The arena itself pulses with malevolence, for the shadow of Ohnd—an ancient abyssal power—lurks within, watching every clash, feeding on hatred and suffering.

To step into this place is to enter a duel not just against a revenant’s wrath, but against the will of the Abyss itself.

This is meant to be a duel a player does against the champion of ohnd after taking the sword from: https://talestavern.com/slab/descent-into-avernus-avernus-hex-map-j4-temple-of-the-broken-prince-ohnd/
