Markus Syzoth, a saurian hidden in plain sight. He lived a normal human life as a shape shifter until that day came. The last day on Earth, as it is commonly known by the last survivors. An apocalyptic event bringing the worst the earth has ever seen. Zombies, monsters, man eating beasts. Humans weren't ready for any of these new threats, nor did they expect to do so. But for Mark, it was just like Zaterra when he was a young hatchling. How will the Saurian fair as a guide to this pseudo Zaterra for four teenage humans.
