Sentinel World
From Warhammer 40k - Lexicanum
A Sentinel World is a new classification of Imperium worlds that were introduced by Lord Commander Guilliman in the aftermath of the Great Rift's creation. They are designed to serve as inviolable bulwarks against the horrors besetting the Imperium Nihilus beyond their aegis.[1a]
