Torna IV

From Memory Alpha, the free Star Trek reference

Torna IV is a planet in the Torna system.

Kor visited a tavern on Torna IV on his way to Deep Space 9 in 2372. In the tavern, he became drunk and revealed that he found a Hur'q cloth that would lead him to the Sword of Kahless. Unfortunately, Toral of the House of Duras was also present and sent a Lethean, Soto, to follow Kor and learn more. (DS9: "The Sword of Kahless")
