Siloportem

 was the capital of the Blood Coteries. Like the later City of the Saved, it was famous for being a multicultural haven, frequented by non-posthuman groups. It was generally regarded as the capital of the decadent universe.

Siloportem was home to many obscure political systems, including gibberism, anathemism, fractal stoicism, and the doctocracy practiced by Malakh XXIII. (PROSE: The Book of the War)

Vedular Ormazd Mostyn was born in Siloportem in 14,413,112.

Some City of the Saved resurrectees thought that the City and Siloportem were similar. (PROSE: Of the City of the Saved...)
