A scorpion-like abomination, about the size of a dog. They live in a colony, headed by a Queen. The beak is not actually their mouth, though they do use it for tearing into their kills. But they don't swallow. The real mouth is actually the hole in their back. They're always out killing whatever they can fine, any way they can - strangulation with their tails, impaling with their bony legs, disemboweling and bludgeoning with their beak. They then tear off chunks of the body and stuff the parts into their mouths with their tails to take back to the Queen. They'll even cart back other Scurge that were killed in the hunt. The workers get whatever fluids drain from the corpses into their mouths, but the Queen gets everything else. The workers are completely blind, relying on vibrations and smell to find victims and their way back to the nest.
