Tantalus

Tantalus is the principle satellite moon of Castobel (aka Halstadt) and a world approximately two thirds the mass of Holy Terra in stable orbit around a type III gas giant. It was an agri-world serving the primary Castobel hive world during the period of established Imperial rulle of the Jericho Sector. Over the last millennia while out of Imperial conntrol, Tantalus has undergone a transition towards a climatic cooling associated with the slow onset of a rotational ice age.

Human life had dwindled considerably during the local 'Age of Shadow' to fewer than then millian living as pre-industrial hunter-gatherers. However, with the coming of the Achilus Crusade and the resurgence of the hive world of Castobel, extensive promethium refinery infrastructure, the starport/city of Tantalus Landing and other settlements have been constructed and the population has trebled through forced immigration of tithed workers and crusade forces.

Tantalus was overrun by the Tyranids in 051 999.M41 and is now a lifeless rock drifting through space.
