Besides, from gamebook 5: "Had it not been for Banedon's timely casting of a spell of illusion, they would be after you still. You cannot help but laugh when you picture their faces, when they saw the Kalkoth leaping at them; thank the gods they did not think to question how a *Kalte ice-beast* came to be roaming the streets of their town".
Instead, in the bestiary they are described as living in many caverns of Magnamund.
Finally, their description doesn't match with the one given in the gamebooks (nor with the picture: http://www.projectaon.org/xhtml/lw/03tcok/sect147.htm), and the plural should be Kalkoth, not Kalkoths.

Sorry for the nitpicking.
