Brief Planetary Information
The capital city of the planet is Helmsdown. Other notable locations include the ruins of the former capital city of Freeport, which was an SLDF logistical depot, and the SLDF weapons depot that it eventually became. This weapons depot was combined with a Castle Brian complex under Nagayan Mountain.
At the dawn of the First Succession War, Minoru Kurita sent troops to raid the world and commandeer the SLDF stockpile. Unable to find the materials left behind by the SLDF, Kurita flew into a rage and ordered his forces to punish the people of Helm. Nuclear weapons rained down on the world, killing over 80% of the population and leaving huge swathes of the planet radioactive deserts. A few AeroSpace Fighter bays located in some asteroids are the only remaining parts of the SLDF fleet base.
The planet was best known for being site of the discovery of the Helm Memory Core in 3028. Helm was granted to the Gray Death Legion as their landhold. Rogue elements from the League and ComStar attempted to manipulate the mercenaries into destroying the Memory Core, but were unsuccessful. The Helm Memory Core was taken to many universities across the Inner Sphere, triggering the technological renaissance of the mid-31st century.
Helm remains a largely agrarian world. Enough of the land has been decontaminated to grow food, and the events of 3028 returned the Yehudan Sea to its place on the surface. (The SLDF had locked the seawaters underground for some reason.)
