Torthalon is the largest of the three main continents of Aralath. It dominates the northern reaches of the world; its north-eastern portion is also called Amallon.

It extends from the western-most of the Settled Lands in the west to far and exotic Osaar on the shores of the great eastern sea. From the north Torthalon extends from the frozen polar wastes far to the south and the tropical heat of Sarvasa, Kastaja and Sulraja.
