Astartes Praeses

Space Marines Portal

The Eye of Terror and its outskirts

The Astartes Praeses were twenty Space Marine Chapters whose main task was to guard the frontiers of the Eye of Terror. By the time of the 13th Black Crusade, the Astartes Praeses numbered eighteen; one of them has been destroyed and another declared excommunicatus traitorus.^[1]

According to the Mythos Angelica Mortis were those chapters founded with the expressed purpose of guarding the regions surrounding the Eye of Terror.^[2]

Thanks to the judgement of Saint Basillius, many of the chapters were sent into the Eye of Terror. In the immediate aftermath of the Abyssal Crusade, the region was wrecked, leading to a perpetual state of siege in the region from then on known Cadian Gate.^[5]

The loss of Cadia and the destruction of the Cadian Gate^[4] leaves the future of the Astartes Praeses order uncertain.

Conflicting sources

• One of the sources on the fate of Astartes Praeses suggests many chapters were declared traitors ^[5].

Another source suggests that these chapters were specifically made to guard the Cadian Gate ^[2].
