Porta Pyrus

Porta Pyrus is a major city in the Calamaran Empire, the Empire's second-largest port and the capital of the Empire's Eastern region, Tormentisto.
Porta Pyrus is one of the three Holy Cities of Navicism, it is here that the holy scriptures of the religion were first transcribed. Being on the Eastern edge of the Shattered Sea, the city has had favourable relations with the nations of Izir, causing it to adopt some of their traditions, such as a reverence of trade and wealth.
Porta Pyrus possessed a number of ingenious structures to manipulate or protect from their local environment. The island Porta Pyrus sits upon is frequently battered by storms, or ash clouds from Duvar, and so possesses high walls, efficient irrigation/guttering systems, and most of the city's buildings have entrances that are raised from the ground.
Porta Pyrus is protected by a pair of ancient Vexii obelisks, which leave living matter intact but destroy any ship which enters their bay by sea.
=== Background ===
The city was originally an Izirian settlement (known as simply Pyrus at the time), until the rise of Ulgard Greenblood and the Calamarans. Pyrus stood strong against his siege for three days, until he summoned a tidal wave to crush the walls and drown the defenders.
