Velthror is a relatively small island, able to hold as few as one pack with large amounts of territory and as many as three packs with small amounts of territory. Water on its frail-rise side dips deeply into the island, creating the Gulf of Velthror and giving Velthror the impression that it is much larger than it is. The territory here is much like a forest, though a thin line around the coast is sandy. Nearby islands are Kosthin, Calib, Falintris, Northir, and Nerrir. It borders on the edges of the Shrosthrin and Sortirre Seas.
