The Halo Effect
by Agentweapon Proelium-Tempus reviews
The UNSC dispatches a small task force to investigate an artefact with origins not of the Orion Arm. The Citadel Races, including the Systems Alliance, are in for an eye opener when two new players in galactic prowess are not only technologically superior but also not bound by the Element Zero and its constraints. Rated T for reasons. AU in both Halo and ME events.
