Once upon a time, the Eternals divided the single world into two equal halves. Since then, half the world has been covered in darkness, while in the other half the sun still shines. But in the darkness, monsters constantly penetrate into the lands of people, which warriors catch and destroy with great difficulty. People try to forever isolate themselves from darkness, considering it an unclean, forever cursed place. But there is one among the people who does not believe that there is nothing behind the darkness. This is Princess Marika, the future queen of the province of Vellia. With unfeminine tenacity, she seeks ways for people to penetrate the hazy, monster-infested veil. What is it that draws the young ruler towards darkness? Perhaps she knows more than others? And will her efforts sooner or later return unity to the world? Or will they destroy him completely?
