Undead Nightmare

The year is 1883. The State of Monroe, once a land of gold strikes, cattle trails, and blood-soaked opportunity, now festers under the weight of a rising evil. It began with a man named Silas Vane—an outlaw turned grave-robber who unearthed a sacred native artifact from beneath the swampy heart of Bordeaux County. Local tribes had long spoken of the artifact in whispers—something not meant to be seen by the living, sealed for centuries beneath layers of water and blood. When Vane took it, something ancient woke. Something hungry. The dead no longer rest. Graves heave open. Smoke and rot cling to the horizon. From the blistering dunes of Redrock to the frozen reaches of Van Colten, the plague spreads like wildfire, carried by riders with torn faces and whispers that gnaw at a man’s sanity. The frontier towns have crumbled, some consumed by fire, others overrun by their own deadfolk. Now, Monroe is a land of factions: survivors turned militias, cults that worship the decay, bounty hunters chasing the infected for coin, and remnants of tribes who remember what was sealed—and what must be done to stop it. Civilization is breaking, but something worse is coming. They say the artifact calls to the west… and hell follows. You are one of the last to still draw breath. Gunslinger, preacher, scout, outlaw—whatever you were before, it means nothing now. What matters is who you’ll become when the soil splits open and the sins of man claw their way out. Whether you ride alone or swear into a faction, you’ll carve your own trail through Monroe’s haunted land. Some fight to survive. Others, to save what’s left. And a few? A few are starting to wonder if the dead can ever be stopped… or if this is just the beginning of the true frontier.
