New Harmony

New Harmony is a human colony world under Unified Earth Government control, unrelated to the colony of Harmony.

History
Spartan-IIIs Catherine-B320 and Jun-A266 were from New Harmony, and their accents suggest it has a large Slavic population. Sometime in the first half of 2537, prior to July 27th, a battle took place on this planet between Covenant and UNSC forces. The UNSC successfully defended the planet and won a rare naval victory. During the battle, a prowler, the, managed to attach a telemetry probe to a retreating Covenant frigate, allowing it to track the ship and locate K7-49.

Locations

 * Monastir
 * Tyumen

Production notes

 * In the Epilogue of Halo 4, Thomas Lasky mentions that he grew up "on" New Harmony. While the preposition suggests he is referring to the colony world, it is more likely that he is meant to be referencing the city of the same name on Mars, which is established to be his homeworld in Halo 4: Forward Unto Dawn; furthermore, it is mentioned in the fourth issue of Halo: Escalation that Lasky grew up with Petra Janecek on Mars, suggesting the use of the preposition "on" was a mistake or that the details of Lasky's background were changed later on in production.
 * The colony may have been named after one of the several towns and communities of the same name in the United States, or the in-universe city of New Harmony on Mars.
