As part of the exchange terms, the Great Mysterium Sect was granted a plot of land in the center of Piraeus City State to construct a grand-scale Dark Temple. The Great Mysterium Sect planned to erect an unprecedented sacrificial hall and altar in the central square of Piraeus City so that all the followers of Hades in the Southern Mediterranean could fulfill their lifelong wishes without needing to make a pilgrimage to the Giganthia Temple on Zago Island.
This was likewise considered a win-win situation for the city officials. Some believers of the Dark Lineage within the city council had long proposed the idea of constructing a temple for worship in the city center. Now, someone had stepped forward with this very idea, and it wouldn't even require municipal funding—only a piece of land designated for religious use. Why would they not be pleased?
