Pyroclast-Gamma-9

An industrial facility and promethium refinery in Tantalus' extreme north, set amid sharp-edged rocks, tumbledown crags and coarse tundra. One of a string of similar facilities scattered across these latitudes, it is a sprawling complex, with numerous buildings, stations and supply dumps spanning several square kilometres in size, although much of its uninhabited infrastructure (such as the chemical storage tanks) is actually buried deep underground beneath the steel domes, pipefarms and dull ferrocrete blockhouses that make up the facility. During full operatios, the area was staffed by a crew of Departmento Munitorum functionaries and technomats, their attendant servitors and a sizable workforce of convict labour kept in check through the use of pain-inducing punishment collars and the overseer's lash.

When the first Tyranid vanguard organisms attacked many of the technomats fled or were killed, leaving the prisoners out of control and the station's servitors on emergency protection programming, but without any form of central control.

It was one of the last places on Tantalus to be overrun by the Tyranids, the cold climate not lending itself to the multiplication of spores. Therefore Magos Vyakai and the remains of an Imperial Guard regiment under the orders of Commissar Sander hoped to find refuge here. Lucky for them Kill-Team Stag was able to extract them from Tantalus before the moon was finally devoured.
