When the Rupture opened and conventional weapons failed against elementally-charged monsters, humanity faced extinction. Those who survived learned a brutal truth: only creature-derived materials could reliably harm creatures. Everything changed. Technology rebuilt itself around this reality, creating a new industrial revolution forged in desperation and blood.
The Discovery
Week One: Conventional firearms, explosives, and military hardware proved largely ineffective. Bullets bounced off elemental auras. Missiles detonated harmlessly against stone-skin. Even when physical damage occurred, creatures regenerated at impossible speeds.
Week Two: A desperate soldier killed a Fire-type creature with a piece of rebar torn from ruins—rebar that had been fused with creature materials during the monster's rampage. The improvised weapon cut through elemental aura like it wasn't there.
Week Three: Researchers confirmed the pattern. Materials infused with elemental energy could bypass elemental defenses. Harvested creature parts could be forged into weapons, armor, and tools that worked where human technology failed.
The Shift: Humanity had its answer. To fight monsters, you needed to harvest monsters. The cycle began: kill creatures, harvest materials, forge better weapons, kill stronger creatures.
Creature Materials and Harvesting
Material Properties
Every part of a slain creature has potential use, though quality varies by origin:
Origin affects quality:
- Rift-born materials: Purest elemental charge, highest quality, most valuable
- Natural-born materials: Strong elemental charge, slightly less pure, still premium
- Infused materials: Weaker elemental charge, impurities from original Earth biology, but abundant
Core Materials (primary harvests):
- Elemental cores: Concentrated energy, power sources
- Scales/hide: Armor plating, protective gear
- Claws/fangs/horns: Weapon components, cutting edges
- Bones: Framework for weapons and armor

The Black Market
Where there's scarcity and desperation, illegal trade flourishes:
Common black market goods:
- Stolen creature materials
- Falsely-graded weapons/armor
- Unlicensed healing salves
- Illegal elemental cores
- Restricted research
- Bonded creature information
Prices:
- Premium over legal markets (50-200% markup)

- No recourse if cheated
- Risk of execution if caught
Who uses it:
- Guildless hunters
- Desperate civilians
- Bonded hunters hiding partners
- Criminals and gangs
- Those city authorities won't help
The Economic Reality
Everything costs more post-Rupture:
- 90% population loss reduced labor force
- Resource scarcity from isolation
- Constant military spending on defense
- Creature materials expensive to acquire
- Technology dependent on dangerous hunting
Result: Vast wealth inequality
- Elite hunters are millionaires
- Skilled workers live comfortably
- Average civilians scrape by
- Failed hunters and unemployed struggle
- Children orphaned by Rupture face poverty
The technology exists to survive. Barely. Whether humanity can thrive again—that question remains unanswered.
The Future
Five years in, humanity has stabilized. The walls hold. Hunters grow more skilled. Technology improves incrementally.
But the creatures keep coming. The rifts don't close. The Wilds don't shrink.
Every technological advance comes from harvested monsters. Every weapon requires killing. Every improvement demands blood.
Humanity survives by becoming predators ourselves.
Maybe that's the price of survival.
Maybe we had no choice.
Maybe we're becoming monsters too.
