The manuscript, written by an old man, details his experiences in an ancient, isolated house with a bad reputation ^{[1] [1]}. He lives alone with his sister and his dog, Pepper ^[1]. The house itself is described as curious and fantastic, with curved towers and a circular body ^[1]. The author recounts a night when his study candles glowed green then red, and he experienced an out-of-body vision ^[1]. He found himself floating through space, observing Earth and other planets, before landing on a vast, desolate

On the Plain of Silence, lit by a gigantic ring of dull-red fire, the author is borne towards a mountain amphitheater ^[1]. There, he discovers a colossal green jade structure, an exact replica of his own house ^[1]. The surrounding mountains are populated by monstrous, seemingly inanimate figures, including mythological deities like Set and Kali, which he perceives as being in a state of

This same luminous growth begins to appear on his own wrist, spreading across his body, filling him with despair ^[1].
