Anura tetrafalmos – a hideous creature from post-nuclear Europe – is commonly called a swamp wolverine. However it is not a mammal from weasel family, although they both have a reputation for ferocity and strength out of proportion to their size, with the documented ability to kill prey many times larger than itself.

The swamp wolverine, or tetrafalm, is a huge and very powerful amphibian predator that lurks near water basins. It can’t stray too far from water because it needs to maintain a certain level of skin moisture to survive. Four eyes on a leathery flattened head make its appearance very distinctive.

Despite its size a wolverine is peculiarly graceful and can move very fast. Its hind legs are very powerful and allow it to jump great distances. The wolverine prefers to hunt alone, stalking its prey for a long time. The outcome of the clash is usually decided by one quick strike of its front claws.

The tetrafalm doesn’t have any apparent weaknesses. Experienced hunters recommend attacking it from long range and never allow it to reach you within a paw strike distance. Swamp wolverine tusks are highly valuable, especially among the Riverers.
