In this world of vast ocean expanses and many islands there are several intelligent races: people, powerful magus - aliens from the stars, marine merra inhabitants and living frigates capable of entering into a mental connection with their captains. For many millennia, a seething cauldron of intrigue, internecine wars and struggle for territory has been boiling, but now the moment is approaching when the fate of the whole world is at stake. Neither a young healer from a remote province, nor the captain of the famous pirate ship "Bride of the Wind," neither the master of a huge empire suffering from a mysterious disease knows about it, and yet the adventure, which began as a cheerful search for an ancient treasure, will eventually lead them, together with friends and allies, into the mouth of the monster and into the very center of the whirlpool, awakened by the formidable deity of the seas and winds, whose name is the Great Storm.
