The planet’s churning, underground volcanoes help produce the system’s main exports: black glass for producing circuitry and a gray oil, the so-called ‘planetblood’ which is used as a high-end space engine lubricant. Both products are exceptionally pure; the “Tat’Ko Seal” graphic which confirms their place of origin is the mark of highly respected products. The polar regions of Tat’ko are a source of bad-ice, a highly illegal frozen combination of water and refinable poisons.
