The Destroyer of Warriors was a huge silver-skinned calot, twice the size of any normal calot, larger and more fearsome than even the largest of banths. It had shining silver teeth, and eyes like red coals.The calot was imprisoned in the catacombs beneath Horz eons ago by the grandsire of Cynthara Dulchis. It took all of his skills and the deaths of a hundred panthans to capture it. The beast was finally slayed by Cynthara and Dan Lan Chee, eons after its imprisonment.
