Trailia, the original planet of the Trailians, existed as a world of limited technology. Positioned within the Trailia system in the Outer Rim Territories, it sat at the edge of charted space and featured dense, overgrown jungles.
Following the planet's subjugation, Emperor's Hand Lord Cronal became the initial discoverer and set up a clandestine laboratory within Trailia's jungles. This lab, protected by both perilous creatures and corrupted inhabitants, served as the location for his experiments aimed at transforming the Trailians into dark warriors. A band of daring adventurers eventually defeated him, though he managed to escape with his life.
