The Mulako Corporation Primordial Water Quarry, also known as Mulako Corporation Quarry, Mulako Corporation comet, MC Quarry, and Mulako quarry, was a comet that orbited its star once every hundred years. For the greater part of this period, the Mulako Corporation mined ice on the comet's surface, extracting pure water from it and selling it to gourmets. When the Mulako Corporation Quarry approached its perihelion and became habitable as a result, the company opened luxurious resorts on the comet for a few months, and tourists visited the warm and humid facilities, with several tourist attractions being available both inside and on the surface.
