Ergastulum

Ergastulum (エルガストルム,) is a city in an unknown country in which the series GANGSTA. takes place.

History
Ergastulum was an isolation camp built in the wake of the War of Unification in 1913. It was originally intended as a quarantine for Cerebret users from the war, later known as Twilights. However, its housing infrastracture was insufficient for the growth of the Twilight population and the facility grew year after year until it eventually encompasses the surrounding area and developed into its own city.

Twilights born outside of Ergastulum, or "Stray Twilights", are targeted by the government to be identified, tagged and relocated to Ergastulum.

In 1926, prison overcrowding caused the government to open Ergastulum to criminals as well, regardless of whether they were Twilights or human. It also became a home for refugees from various countries. Because of this there is a high amount of racial and ethnic diversity in Ergastulum.

The Paulklee Guild's foundation established by Adolf Paulklee in 1934 raised the social status of Twilights by organizing them into a mercenary guild for hire. The Twilight slavery was dismantled. A request and dispatch system was set up so Twilights could only be contracted to a client for the duration of a job. As a result, Twilights were able to regain their status in Ergastulum.

Following a period of unrest, Ergastulum enjoyed relative stability during the early '70s due to an understanding between all four families (Corsica, Monroe, Cristiano, amd Paulklee). However, violence perpetrated by Normals against Twilights including the sexual assault of female Twilights which is followed by Twilight retaliation.

This short-lived peace gave way to further Anti-Twilightss resistance in the '80s, beginning with protests at the four city gates and leading to Twilightss hunts within the city. The government employed mercenaries alongside national troops to suppress the rebellion. The instability culminated in a notable incident in '89.
