The Imperial Aquila

A Sentinel World, also sometimes called a Bastion World, is an Imperial planet that has been designated to serve as an inviolable bulwark of the Emperor of Mankind's order within the region of the galaxy known as the Imperium Nihilus. Sentinel Worlds are expected to defend themselves against all the horrors assaulting the Dark Imperium beyond their aegis since it was cut off from the rest of the Emperor's realm with the birth of the Great Rift.

The designation of Sentinel World is a new one created on the order of the Lord Commander of the Imperium Roboute Guilliman after his resurrection.

Vigilus is one of the most notable of such Sentinel Worlds, lying as it does at the mouth of the Nachmund Gauntlet -- the only known stable route through the Cicatrix Maledictum.

Planet Name
Vigilus Segmentum Ultima Unknown Unknown Unknown Unknown Vigilus is an Imperial Hive World that represents the terminus of a key route through the Great Rift into the Imperium Nihilus. As a result, Vigilus has become a heavily contested strategic location and the source of conflict between several of the different starfaring species and factions of the Milky Way Galaxy in the early 42nd Millennium. The campaign to claim Vigilus became known as the War of Beasts.
