The Event Group is the most secret organization in the United States. Its task is to discover the real background of myths and legends of world history. But it happens that these myths and legends come to life and come to people on their own... For several centuries, the Ertal family, researchers and scientists, sought to put their ingenious inventions at the service of peaceful humanity. And it continued to wage bloody wars and destroy the world around us. And then Alexandria Ertal decided that goodness should acquire heavy fists. She and her followers built a gigantic underwater vessel, the likes of which has never been seen in history, and named it Leviathan. It received this name in honor of the submarine of its ancestor, which Alexandre Dumas once saw and described in his novel as “Nautilus”. With the help of the Leviathan, whose power no fleet in the world can resist, Ertal hopes to bring cruel humanity to its knees. The Event group, of course, stands for world peace, but not at the same price...
