Author's abstract Greetings, dear Reader! I want to tell you everything that is connected with the kingdom I invented, called Sulfur, now... Sulfur, the once beautiful land of three kings, now belongs to the demon Arachne. His children, monstrous marlogs who live in the underground Ulhur-labyrinth, at the will of their father, unleash their rage on the disobedient. The power of his daughters is limitless. And for hundreds of years, human blood has been shed on the altars, and prayers have been offered to the vile deity of the arachnids. Place of action: A fictional kingdom formed by several peoples: the arachnids - servants of the demon Arachne and the marlogs - ugly half-humans born from Arachne himself; Antigus - the people of the kingdom of Antavia; Cornuoths - horned people living in the forest principality of Arbosh. Power belongs to the arachnids, who enslaved the Antigus and Cornuots. On the throne of Antavia is the first priest Arachne Khorkh. About him and about the formation of Sulfur in the first book "Sulfur. The Key to the Abyss"
