Dayos IV

Dayos IV is a small Klingon colony near the Empire's border with the Federation. In addition to the small Klingon population, Dayos is also home to a small group of expatriate Zarnac - the Thirty-first House.

The colony was the site of the Battle of Dayos IV in 2378, when a large number of the colonists were massacred by Zarnac forces intent on wiping out the exiles.

In the later years of his life, Dahar master Karn lived on Dayos IV. He perished in the Zarnac attack, giving his life defending the colony.
