There is a Furok den within the limits of Glacern. It is accessible by way of secret passage from the basement of an elevated house; this passage is opened by smashing a weak brick façade, which reveals a warm limestone cave with stalactites, stalagmites, liquid water, and a strange ambient red glow. An opening on the other side of this cave leads to a snow-covered ledge above a forest; here can be found two Furok Slashers.
