El Bisabuelo took the mystical housemaid as a concubine. She gave birth to la Fuente's mother, Ana Portilla, who married a half Italian, Martín Bachio. AP gave birth to the girl, la Fuente. The girl was raped by el Bisabuelo. This produced a boy, later to be known as el Patroncito. When Martín discovered this he burned down the famous Hacienda La Fuente, killing el Bisabuelo and much of his family. The servants quarters survived as the only remnants of Hacienda La Fuente. La muchacha india used to sleep in the room where la Fuente sleeps. Martín was hanged by los rurales, vigilante leftovers from Porfirio Diaz and the porfiriata.
La Fuente remained in the remnants of the hacienda, in the room over the water works (las obras hidraulicas). Her son was taken and raised by la Bisabuela's family in San Cristobal de las Casas. There the boy became old quickly. He became el Patroncito, the lord of the burnt estate. His mother was cared for by the remaining servants at the estate, themselves related to la muchacha india (Guatemala). El Patroncito grew up twisted and obsessed with his birth right. La Fuente sunk into her fertile, primordial ooze and reformed herself. She was reborn, just cells at a time.
The boy is the great grand nephew of el Patroncito. His grandmother was a cousin to el Patroncito.
The dogs created each opportunity for the horrors of fate to compile and intervene. These details I'll leave to the writing.
