Kask-Kirrulthar is the largest of the three cyclops watchtowers from the age of the Koloran Empire, though it stands at the same height as Fralros and Hask-Ultharan. Located in western Iobaria, the tower is inhabited by wraith-like creatures, who vary in appearance and size from human children to dragons, and hunt the surrounding lands out to two miles for the living on nights when the moon does not shine in the sky.1
