The Essentiae Household, surrounding desert, and Abandoned Biomechanical Testing Lab are some of the relatively few fixed locations in Vale.
It was built by Integer Essentiae ~40 years before PSitME.
Ax and Emma lived here, with the house gaining more residents throughout Season 1.
Between seasons, it housed Nicole and Lilian Essentiae.
As of so far in season two, it functions as sort of a headquarters for the heroes.
