These sharks dwell in the deepest seas, only traveling near the surface to gather enough food to survive. Their largest teeth are over a foot long and capable of breaking through the hull of a ship. Academics call these ancient monsters megalodons, but for the normal folk they are widely known as deep terror sharks.
Ancient Guardians. Deep terrors were created long ago to protect long-forgotten civilizations. Now, these guardians patrol ancient ruins, protecting the treasures they hold from those who dare to trespass. Once a day a deep terror leaves its ruins to hunt.
A Shadow in the Sea. The first sign of a deep terror hunting near the surface is the sighting of a massive shadowy object moving quickly below the surface. By the time its fin appears, this shark has already begun its attack.
