Great Ungeness Trench

The Great Ungeness Trench was an underwater trench on the ocean-world of Mon Cala. Around 18 BBY after the Battle of Dac City destroyed Dac City and Imperial military forces, Dark Lord of the Sith Darth Vader sunk to the trench, and faced a large squid creature.

Behind the scenes
The Great Ungeness Trench is slated to appear in Darth Vader: Dark Lord of the Sith 15: Burning Seas, Part III, a 2018 canon comic written by Charles Soule and pencilled by Giuseppe Camuncoli.
