- Kruthiks are chitinous reptilian hunters that form small hives underground. They use their superior numbers to overwhelm and devour all other nearby creatures. Kruthiks hunt methodically, stripping one area of prey before expanding their territory. They butcher their kills and carry treasure back to their nesting warrens. Mauled carcasses and strange tracks that look as if they were made by spikes are sure signs of a kruthik horde.
- Kruthiks communicate with one another through a complex series of insectlike chitters and reptilian hisses. These sounds can often be heard in advance of a kruthik attack. Kruthiks hatch from eggs and undergo several metamorphoses during their life cycle. Hatchlings grow into young, but young and adults enter a hard cocoon to change into the next larger breed of kruthik.
