The Thorndelle Mountains are a large mountain range cutting across central Kalor, on the world of Lezaria. Flyland and Rascalanse lie to the west, Hannaderres lies to the east, and Hlaya to the south. To the north, the Thorndelles split around the valley of Tanivalis.

Aurora Core is one of the most powerful nodes on Lezaria, and is located near the southernmost point of Tanivalis, not far from the ruins of the city of Aurora.[1] This node houses the Gates of Time.[2]

Thorn Valley is another node located near the source of the River Roulden, east of Wishingsdale. It is home to a sept of werewolves who consider it their caern. [3]
