In the far southern country of Jundea, a terrible disaster happened: a star fell from the sky, giving birth to the Death Zone... King of High Boria Klim the Dragon Slayer and his battle team - the court jester, the genie Bahlul and the Bayun cat - immediately set off on a campaign. They will have to cross mountains, steppes, forest wilds, and on the way back dangerous seas, and along the way they will meet robbers, mermaids, witches, sirens and other amazing creatures. The fight against the creatures from the Death Zone will require Klim’s courage and cunning, but he will win and receive a reward from the ruler of Jundea, the mysterious, multifaceted Presbyter John.
