Hitora colony

From Memory Alpha, the free Star Trek reference

The Hitora colony is a Klingon colony that lies on the outer reaches of the Empire. In 2370 Kurn was dispatched to the colony as Gowron's representative from the High Council. (TNG: "Firstborn")

According to K'mtar a message sent to Kurn would take several days because he was at the Hitora colony. However, given K'mtar's other deceptions it is possible that Kurn was not, in fact, sent to the colony as claimed.
