The Octarius Sector has been host to a seemingly endless conflict between Tyranids and Orks. Neither side has been able to secure an advantage, but the resulting destruction continues to spread, threatening to reach wider than the Imperium can hope to control.

In this narrative supplement, you can dive into the lore around Octarius, and experience it through your own campaign with rules provided within, with a majority focused on Crusade content.

A copy of the Warhammer 40,000 Core Rulebook will be required to use this supplement.
