It was late at night, in the basement of the Cloister of Cavern. There was a stove, from which smoke of sulphur slowly and consistently crawled out and soon spread into the whole basement. At the same time, many different illusions of hell appeared in the dancing fire.
The hydrargyrum was flowing in the groove on the ground and formed a complex Alchemy Array. The array extended in all directions and even spread to the ceiling. At last, it gathered around the bizarre "stove."
With the smoke and the array, the whole space of the basement was twisted and became non-physical magic world. The music theory of the School of Abstinence filled this room and began absorbing the energy from the aether stove. All the rules of the Physical World changed completely, and this place became a projection of the Aether World.
In the basement, the old musician Mandel was playing his Mandolin. The string trembled, making a peculiar sound.
