Alsijn

Alsijn (アルシジン) (Arabic: السجن; literally The Prison) is a prison in a desert in an unknown location. It has reportedly been around for ages, home to many dangerous inmates and was regarded as virtually inescapable. However, one year after Hunter Bradley was imprisoned there, a massive prison break occurred and Alsijn was partially destroyed. Hunter managed to escape, established himself in North City as the vigilante Arsenal.
