Heian (Earth-5875)

Heian is a Covenant world, much farther from the most distant human Outer colony. It features an Earth-like environment and atmosphere. Meteor showers are common occurences on the planet.

History
Because the planet was the site of an important Covenant settlement headed by the Minister of Agriculture, the UNSC dispatched a team of four ODSTs and a SPARTAN-II to the colony during the First Contact War to assassinate the san'shyuum minister, which would cause a hole in the Covenant food supply across the system and the sector. During the mission, they were also ordered to gather intelligence on the unknown ruins that existed through the planet. While the ODSTs were succesful, the mission came at the cost of the lives of Cal-141 and Mark Checkman. The photographs taken by the ODSTs were later sent to the University of Edinburgh as a part of an investigation of forerunner relics.
