Urdas are a people who are part Gnome, part Troll. They live deep in the Northland and are not found south of the Charnal Mountains. They are a highly insular people whom even Rock Trolls regard as primitive savages. Quickening and her party encounter them on the way to Eldwist when they are caught by hundreds of Urdas in the Spikes, a forested valley within the Charnals characterized by a ridgeline of dead, spike-like trees running down its center.
