Battle of Meridian (2558)

The Battle of Meridian was an engagement of a two four spartan fireteams from the United Nations Space Command and the Liang-Dortmund Corporation and the Created on October 25, 2558.

Background
After going AWOL, Master Chief and Blue team land on Meridian to find Cortana and bring her home.

The battle
It is unknown if Blue team engaged the Created or not but we do know that Osiris team did. As soon as Osiris took the space elevator down to the surface, they were immediately welcomed by Prometheans. With assistance from Liang-Dortmund Corporation, Osiris drived enemy forces away from town. Later, Osiris caught up with Blue team and Agent Locke attempted to arrest them. After Master Chief rose victorious from a brawl that he and Locke fought, Chief walked through a teleporter into the Guardian.

Blue Team and Fireteam Osiris
Blue Team's Guardian would eventually arrive on Genesis, a Forerunner Builder planet in the Nomos system, where they would discover other Guardians, meet the Warden Eternal, and learn of Cortana's survival and her plan for the enforcement of the Mantle on the galaxy.

In parallel, Fireteam Osiris would retreat back to Infinity. Roland analyzed data acquired from Meridian's Guardian, and Captain Lasky and Dr Halsey devised a plan to use another Guardian, on Sanghelios, to join up with Blue Team. They would thus meet up with the Arbiter and the Swords of Sanghelios.

Activities on Meridian
Despite the loss of the orbital elevator and of its local headquarters, Liang-Dortmung still received important demand for Meridian's vitrified resources. They relocated their efforts to Darkstar Station, a remote polar outpost. Its workers and engineers had remained mostly unaware of the catastrophe that had happened on the other surface of the planet-moon. The company sent additional ships and personnel to accelerate resource gathering as long as possible, profiting from a tacit permission from the UNSC, and the lack of risky Created activity in the system. Still, the UNSC would prepare a return to Meridian in order to investigate ancient machinery dormant under the surface.
