Overview

On the dead world of Vosmos, elites from across the void descend to bet on bloodsport: gladiators, animal fights, and road-warrior events. Neon arenas glow atop ruined megacities; necro-tech hums beneath every blade and cage. Grimdark magic, biotech, and psionics fuse with brutal spectacle as factions vie for power, profit, and immortality through ritual power.

Setting

The Blood Spire Arena is the crown of a sprawling underworld economy. Surrounding districts host the Maelstrom Market, Neon Wastes, and the Rust Sea. Society tolerates, even celebrates, this cruelty; nothing is frowned upon openly—until someone dares expose the rot. The planet’s core persists only because a ritual Engine feeds on life, keeping Vosmos from final ruin and funding the syndicate’s appetite.

Main Quest

The PCs are hired to infiltrate the Crown, the syndicate that runs the fights. Their mission: topple the betting empire, liberate the captive combatants, and sabotage the Engine before the ritual awakens Vosmos’ heart and rebinds the world to the Crown’s will. Time presses as a planned final event tightens its grip on reality.

Side Quests

• Rescue a celebrated fighter who knows critical weaknesses of the Engine; loyalty may hinge on a choice to risk everything.


• Sabotage shipments of glory ore—the enchanted fuel powering the arena’s most lethal spectacles.


• Seek a rogue artificer who can rewire the Engine’s core, revealing the planet’s true fate and offering a path to freedom or ruin.

Key Locations

• Blood Spire Arena: central stage, seat of power, and hive of conspiracies.


• Maelstrom Market: illegal tech, data-dogs, and debt contracts.


• Neon Wastes: scavenger frontier where factions hunt for upgrades and allies.


• Rust Sea: a corrosion-blackened inland sea, home to smugglers and forgotten routes.

Hooks & Challenges

Rumors whisper of a Quiet Hand ready to end the blood games. Eligibility, debt traps, and tempting bargains pull the party toward moral ambiguity as they decide between personal gain and the greater good.

Rewards

Cybernetic implants, forged relics, and influence over liberated pit-creatures. If the Engine is halted, the PCs may gain control over a portion of Vosmos’ fate or spark a rebellion that could reshape the planet’s dark future.
