Quarlo I'Shibix, an administrator at a mine, was employed by Mon Tondievz, Ltd. on the planet of Krann. In addition to his official duties, he ran a profitable eldratz spice operation. While the spice trade was his primary source of income, I'Shibix also utilized it to control enslaved Kluuzot laborers, compelling them to mine nova crystals. Once the spice's effects rendered a worker too impaired to continue, I'Shibix would set the Kluuzot free.
