A Jungle Beyond Time. A Sky Full of Teeth. A Mystery Waiting to Swallow You.
“There was a time when men believed the world was mapped. They were wrong.”
Lost World: Dinosaur Island is a full-length sandbox campaign setting for the Vaesen RPG, inspired by pulp science adventure, survival horror, and Edwardian airship expeditions. Players descend into the storm-wracked skies of Isla Verelia, a place lost to maps but alive with prehistoric danger, colonial secrets, and the uncanny thrum of something ancient beneath the canopy.
Instead of haunted manors and Nordic spirits, you’ll confront living fossils, whispering ruins, and dirigibles that groan through fog-choked skies. This is a new kind of horror: primal, uncertain, and vast.
Inside this 78-page book, you’ll find:
Dinosaur Bestiary grounded in naturalist logic, not fantasy tropes
Rules for Dirigibles – mooring towers, aerial hazards, mechanical failures
Island Map with exploration mechanics and region-based secrets
New Roles – Naturalist, Jungle Scout, Balloon Mechanic, and more
Campaign Frameworks & Scenario Hooks including a full starter mystery: The Bones of Flight
Factions – including stranded scientists, rogue traders, and indigenous survivors
Random Tables – weather shifts, jungle events, dinosaur migrations, and airship encounters
Themes include:
• Scientific hubris and the illusion of control
• Colonial intrusion and ecological reverence
• Survival, camaraderie, and psychological decay
• Deep time and temporal dislocation
Compatible with Vaesen, this book is also easily adapted to systems like Tales from the Loop, Things from the Flood, Call of Cthulhu, MAJESTIC, Rise of R’lyeh, Forbidden Lands, or Savage Worlds. Whether you’re piloting a creaking dirigible, cataloguing thunder-lizards, or fleeing something that was never meant to wake, The Island harbours untold secrets.
