Kaldra IV

From Memory Alpha, the free Star Trek reference.

Kaldra IV is the fourth planet in the Kaldra system. The USS Enterprise-D was transporting three Ullian telepathic historians to this planet in 2368, whose inhabitants they hoped to add to their library of individual memories. However, the Enterprise was diverted to the Ullian homeworld after Jev's perpetration of telepathic memory invasion was discovered. (TNG: "Violations")

Kalrda IV appeared on a star chart in astrometrics in VOY: "Child's Play" and "The Haunting of Deck Twelve".
