The Bolgar were a species of extra-dimensional beings at war with the Teuthis. They resembled giant amphibians, with thick green skin that seemed to hang loosely off their teardrop-shaped bodies and were covered in slime that dripped to the ground. They had no visible legs, which were hidden by the massive folds of their bodies. They also had four arms, which were jointed in the middle but were also rail-thin. Large swelling bulges and the ends could be considered hands, and half a dozen small, dangling, string-like appendages on each "hand" served as fingers.
