Lorassyon is the second largest of the Lorathi isles.
The ancient mazemakers constructed a great labyrinth at Lorassyon, covering three quarters of the island's surface and having four subterranean levels.
The seat of Qarlon the Great was a wooden keep at the center of Lorassyon's maze. The keep was destroyed by Valyrian dragonlords during the Scouring of Lorath.
When the smallfolk of the isles overthrew the disciples of Boash, the only surviving acolytes were those who fled to Lorassyon. They died out almost a century later.
