The series also shares a direct narrative connection with Halo: Shadows of Reach, with its characters and events leading directly into Halo: Divine Wind. It also shares a narrative connection to the short story Sacrifice as the Covenant loyalists appear in Halo: Divine Wind.

Halo: Divine Wind has narrative connections to Halo Wars 2, continuing the story started there. Halo: Retribution has narrative connections to Halo 5: Guardians, specifically the events aboard Argent Moon in the level Blue Team.

All of the novels in the series feature the Forerunner archeon-class ancilla Intrepid Eye as well as the Covenant remnant the Keepers of the One Freedom and its leader Castor as major recurring antagonists.
