Deep within the abandoned, dormant craters of old volcanoes, a unique and deadly creature lurks. Known as the Hollow Jaw, these fearsome beasts have evolved to survive in the harshest and most unforgiving of environments. At first glance, the Hollow Jaw appears unremarkable, resembling a small, tailless lizard with a gaping maw that seems almost comically oversized. But this seemingly innocuous appearance belies the creature's true nature as a ruthless predator, waiting patiently in its chosen crater for unsuspecting prey to stumble into its trap. The Hollow Jaw's mouth is its most distinctive feature, with a rough, stone-like interior that matches perfectly with its grey teeth. The outside skin, however, is surprisingly soft to the touch. When the creature is still small, it can move about nimbly on its small legs, scouting for the perfect location to settle down and begin its ambush. Once it has found a suitable crater, the Hollow Jaw lies in wait, mouth agape, poised to snap shut at the first sign of movement. Using sheer force, the Hollow Jaw crushes its prey in its powerful jaws. The creature requires surprisingly little sustenance to survive, as it grows to fill the entire crater. Its mouth and stomach expand dramatically, while its legs quickly deteriorate, rendering it immobile. The Hollow Jaw is known to live for ages, with no maximum size yet discovered. Although limited in size by the boundaries of its chosen crater, it is unknown just how large these beasts can become. Rumors abound of the Hollow Jaw settling in the craters of dormant volcanoes, but no one can say for sure. Regardless, this elusive predator remains a formidable foe, striking fear into the hearts of all who dare to venture near its domain.
