ABOUT

Silence fills the air near a busy oasis. Animals listen more intently as they know a predator has moved into the area. Then without warning, an immense creature smashes out of the ground. The giant sand shark has surfaced to hunt anything and everything.

Sum of All Fears. Many that live in the desert tell tales of a monster too big to believe. However, the stories are true. The giant sand shark travels under the sand hunting for its next meal.

On the Move. It is almost always on the move. However, this titan does rest for periods, slumbering deep below the dunes. Some say its lair is a gigantic, subterranean cavern. An eccentric gnome wizard is said to visit the monstrosity.

Desert Diet. This carnivorous titan will feed on beasts, humanoids, and even other monsters. It has no interest in feeding on plants, so its wellsuited to the desert.
