Mendel

Mendel IV, better known simply as Mendel, is the forth planet of Lalande 46650 (Also referred to as the Mendel system). The planet, which was colonized in 2401, is a warm planet with no ice caps and covered mostly by ocean. The dominating land features of Mendel are a two continents, and a sporadic assortment of islands, not that dissimilar to Oceania. One only continent, Norda, was terraformed early in the planet's development to make Mendel a wildlife reserve planet. The continent of Suda was not terraformed as a decent nomadic population having already established a series of mining communities.

Mendel would become known as a hot spot for Insurrectionist sympathies during the late 25th century, and Early 26th century. Particularly, it would be referred to as the birthplace of the Unified Workers Left, a far-left offshoot of the Insurrection championed by Insurrectionist Leader and Terrorist Maya Astor. The local UWL cells would be become a dominant regional power in Suda, adopting the faction name of the Mendelian Worker's Army in 2525.

Mendel would also be the site of a battle in the Human-Covenant War: The Battle of Mendel IV. The battle would fought between Local Human forces, including DIAMOND Team, and The Fleet of Specular Piety commanded by the Minor Prophet of Scorn and Brute Chieftan Kulljul.

Human-Covenant War
When the Human-Covenant War cut the planet off from the rest of the Inner Colonies, the UNSC Colonial Government slowly lost power. Particularly in Gregor City, where 90% of the popularion resided, a combination of Street Gangs, Local Police, Community Organizers, and the MWA split up the city. The MWA in particular would control vast swaths of Gregor City and all of Suda. The small UNSC garrison resided to fall back to the Gregor City Tether, and escaped to orbit and left the system shortly after.
