Trailia was a low-tech planet, located in the Trailia system of the Outer Rim Territories, on the fringes of known space. It was the homeworld of the Trailians. It was a technologically unadvanced world with thick jungles.
Emperor's Hand Lord Cronal had a hidden laboratory in the planet's jungles, guarded by dangerous animals and twisted villagers, where he experimented on transforming the Trailians into a race of dark warriors. He was defeated by a group of adventurers, but survived the encounter.
