Common Names: Club-Tail, Living Anvil, Smasher
Diet: Herbivore
Habitat: Lowland swamps, dense brush, and floodplains.
A low-slung, heavily built quadruped, the Testudo ferreus is a walking fortress. Its entire dorsal surface is covered in dense, interlocking bony plates (osteoderms) that fuse into a solid carapace. Its tail ends in a massive, fused bone-club that can weigh over a hundred kilograms.
They are slow-moving, solitary grazers, content to spend their days stripping low-hanging foliage and chewing tough roots. They are incredibly docile unless directly provoked. If threatened, they will hunker down, protecting their softer underbelly, and wait for the predator to step within range of their tail. A single swing from a Testudo club can shatter the femur of a Gigas carnifex or cave in the side of an armored steam-wagon.
They are entirely ignored by local predators and most humans. However, the bony plates covering their backs are miraculously dense while remaining relatively lightweight. A highly lucrative black market has emerged among frontier poachers who hunt them (usually utilizing explosives or neurotoxins) to harvest the armor. These plates are sold in Thalessa and Lusavhara to be fashioned into bullet-resistant breastplates for elite shock-infantry, or as luxury armor-plating for the carriages of paranoid robber barons.
