Parakrekk

Parakrekk were vicious amphibians that followed in the wake of the Protocairns, feeding off of the rubble the larger creatures leave behind. Long after the Protocairns had died, these nasty beings lingered, tearing down structures with their claws and feasting on the fragments. Extremely good at finding concealment, they were very difficult to root out once they had gotten a foothold in a place. Left unchecked, they would eventually destroy an entire city due to their ravenous appetite.
