Zupponn Mining Co.
One day, just outside the reaches of Scythian space, a ragtag group of heavily armored mercenaries landed on a patch of asteroids. When the Scythians investigated, they learned that the group was led by one known as Zupponn and they called themselves the Zupponn Mining Co. Zupponn claimed to be interested in studying the Green Transparent ore that resided in the asteroids, and the Scythians, feeling that the near-worthless material had little to no value to them, allowed them to go about their business.
It was not long before the ZMC had discovered a unique way to refine the ore and extract its latent properties. They started experimenting with the ore's applications in weapon development and soon they created Zupponn's personal power mace, which was powered purely by Green Transparent. This was followed by many other weapons and rapid expansion by the ZMC to other similar asteroid patches.
Deal With the Immortals
The ZMC was largely neutral in the politics of the Brikverse until the invasion of Fico by the Immortals. The Immortal Warhead contacted Zupponn and offered the ZMC a lucrative contract for the services of a large amount of ZMC mercs. The first few waves of the mercs were mostly donned in a wide variety of heavy armor and armed with an even wider variety of weapons, but it wasn't long before the ZMC's current Black and Green Transparent color scheme was adopted.
The Allied Nations
When the Allied Nations popped up in G.R. 2012, the ZMC was included even though they technically weren't a nation. The potential for a quick profit was seen and the ZMC offered military services to the AN in exchange for a great deal of money and resources. Through this relationship, the ZMC became involved in the Avalonian Conflict and the subsequent Mengguu Revolution and also used its position within the AN and its recent gain in resources to claim a virtual monopoly over the Green Transparent market.
With all that behind them as the AN has since been destroyed, the ZMC is constantly looking for opportunities to make more profit and expand their operations. Expansion has already begun in Green Transparent reactor technology, which should be very big in the ZMC's future.
