Lentonia

Lentonia was a planet to which no segmentum or coordinates are attested in surviving records.

In 938.M41 the Valhallan 597th Regiment, together with Commissar Ciaphas Cain, was sent to the world.

The posting led to the events recorded as the Lentonia outbreak, in which Cain and the regiment encountered a warp-tainted infection among Imperial forces.
