Harriet Flamel, a young alchemist in 16th-century Prague, inherits a fragment of the Magisterium, a dark matter artifact created by her grandfather Nicholas. When her first experiment fails in front of Professor Dee, the shame drives her further than caution should allow.
Her experiment succeeds: lightning strikes the artifact and the stone transforms.
Her success becomes a point of no return: the Magisterium begins assimilating her, phase by phase, following the seven stages of the Philosopher’s Stone creation— from Ignis (Spark) to Mortificatio (Silence). As Harriet documents her dissolution in diary entries, she loses her identity, and finally her sense of where her body ends and the substance begins.
The Formula Incarnate is a dark fantasy short story about the cost of triumph, the theft of authorship, and the grief that runs beneath both.
