Over the last five years Cryptic have introduced a variety of themed lock boxes into Star Trek Online. Each type of lock box has only been available for a limited period of time, thus making much of their contents quite rare. Naturally this has led to a booming market based on the trading these items. Consoles such as Plasmonic Leech and such ships at the Wells Temporal Science Vessel have regularly sold on the exchange for hundreds of millions of energy credits along with other scarce rewards. STO has long been a haven for commodity speculators and even led to an illicit trade outside of the game where rare items are sold for real money.
