Native to the rivers and open sea in Stormwater, Hullbacks are an oversized natural variant of turtles and tortoises and were sacred to the Giants of Stormwater, who used their shells to make shields and are equally important to the people of Stormwater, who adopted this armored creature into their flag and royal sigil.
Omnivorous, and hibernating in coastal caves, marshlands and large rivers during the colder months, they are only typically active for a few months every year, and while they largely eat plants, insects, fish, frogs and carrion, they will attempt to eat anything that they can fit into their mouths.
While generally not a direct threat to humans, they can and will attack if stepped on or otherwise provoked. Like with the Giants themselves, there are some that seem to grow to gargantuan proportions, and their thick hides and almost impenetrable shells make them extremely dangerous. For unlike the Giants, who the bigger they are, the more placid by nature they tend to be, Gargantuan Hullbanks are ravenous and capable of destroying entire villages in a few short hours.
Thankfully, Gargantuan Hullbacks are extremely rare, but the common Hullback is frequently encountered in Stormwater and generally left well alone, the shells collected only after they have died, for hunting them is outlawed and killing one that is not aggressive is a serious crime punishable by exile.
