Onyx Sky

Onyx Sky explores our world after a devastating global war and environmental collapse plunge humanity back into the stone age.

In Onyx Sky, players create characters who’ve been safe inside a military bunker, government facility, fallout shelter, or scientific vault. After decades hidden away, they emerge from their haven.

They find a world in ruin, its communities struggling to endure against roaming marauders, autonomous battle droids, and metal-eating nanites.

The players’ characters, armed with contemporary knowledge and ideals, are thrust into a world in technological and cultural freefall.

Onyx Sky, from the ENnie award-winning designer of Hero KidsForge Engine, and Heroes Against Darkness, is:

  • All In One RPG: Everything you need to play a campaign; Player Content, Game Rules, GM Guidance, Campaign Guide, and Adversaries.

Onyx Sky’s Setting takes players into our near-future:

  • In Decay: Microscopic nanites consume metal to replicate themselves, stripping the world of metal piece by piece.
  • Naive Newcomers: The players’ characters emerge into this world after three decades sheltering safely in a fallout shelter, military facility, survival bunker, or research.
  • Relentless Droids: Military battle droids roam the land, seaching indescriminately for targets.

Onyx Sky’s Adversaries section includes 78 challenging and versatile animals, droids, and humans:

  • Animals: With the human population greatly reduced, animal predators are resurgent, including big cats, bears, snakes, wolves and dogs, hyena, and more.
  • Droids: During the great war, the military-industial complex perfected autonomous battle droids; simple workhorses, experimental hunter-killers, drones, and huge titan-class units.
  • Humans: In the devastated world, other survivors might be allies or enemies, with adversaries including bandits, ferals, cannibals, slavers, reavers, nutes, neonates, militia, and cultists.
