A mining planet where La'an uncovered a cabal of former Starfleet and Klingon soldiers plotting to restart the Klingon War.
Cajitar IV is the mining planet where security chief La'an Noonien-Singh sends a distress call in The Broken Circle. With Number One under arrest, Spock disobeys Admiral Robert April and takes the Enterprise to find her.
La'an explains that a cabal of former Starfleet and Klingon soldiers is plotting to restart the recently ended war by attacking a Klingon ship with a vessel cobbled together from Starfleet technology. Joseph M'Benga and Christine Chapel are captured and taken aboard, but they fight their way off just before Spock orders the false flag ship destroyed.
