Background: Until Cerulean Gemstones were found on Corinthias it had little to offer. Until that point the planet had only produced low grade ores for the Tri-System market. Now, however, this planet is one of the Confederations most valued assets. The Government leases 5 year mining rights to companies. At the moment the lease revenues pay for 10% of all the Confederations expenditure, while the companies which have those rights are some of the most powerful and wealthy in the Tri-System.
