Varangantua

Varangantua is a huge hive city on the planet Alecto in Segmentum Tempestus. It is the setting for the Warhammer Crime stories published by Black Library.

Alecto itself was colonized back in the Dark Age of Technology. It is apparently far from any meaningful front lines - most of its people don't even think Xenos actually exist or know much about anything going on in the greater Imperium. The Mechanicus maintain numerous enclaves in the city, serving the "nearby" forgeworld of Zhao-Arkkad.

Its upper class is full of scheming bastards, and everyone else is downtrodden and desperate. The local enforcers, the Sanctioners, have their work cut out trying to keep everything going. There are organ legging gangs, cannibal cults, revolutionaries, and all sorts of nastiness everywhere.

So basically like most other Hive Worlds.
