Their blood fuses and activates the ancient Star Covenant that links their life energy. Ethan discovers his mentor Marcus colludes with the usurper star lord, using him—the Covenant host—as bait.

Teaming up with double agent Naia, ex-soldier Riley and Dominic, son of the usurper, they unravel the massive conspiracy spanning Earth and interstellar realms, breaking the chains of royal blood and the Star Core to forge equal coexistence between two civilizations.
