The Cycle marches ever onward. 100,000 years ago a race virtually unknown to Citadel space established an Empire that spanned the galaxy. Two Cycles later, their ruins gave rise to a Covenant bound in their worship. These aliens evolved outside of the Reapers' plan, and now threaten to upset it as their gods had eons before.

Rise of the Terran Alliance by EightEqualsEqualsDee reviews
