Trench was a Harch admiral and naval commander who survived a number of presumed deaths throughout his career. Hailing from Secundus Ando, he acquitted himself in engagements with the Galactic Republic, all the while savoring the terror he struck in his enemies. Years after his purported death at the Battle of Malastare Narrows, he resurfaced during the Clone Wars, becoming a key officer in the navy of the Confederacy of Independent Systems. From the dreadnought Invincible he oversaw the Confederate blockade of Christophsis, which brought him into conflict with a Republic battle group led by Jedi Generals Obi-Wan Kenobi and Anakin Skywalker along with an old foe, Admiral Wullf Yularen. When Skywalker and Yularen attempted to use an experimental stealth ship to breach the blockade, Trench began a deadly game of cat and mouse with them. Though Skywalker outwitted him by redirecting a volley of tracking torpedoes at the Invincible, Trench managed to survive his flagship’s demise.
