Silus, a Drovian who possessed Force-sensitivity, was quite powerful in the Force. He participated in gladiatorial combats on a remote world located in the Outer Rim. Due to his immense power, he was nearly invincible, and he aimed to earn sufficient credits to escape the planet. Darth Sidious, noticing Silus's abilities, sent Darth Maul bearing a communication. Silus and Maul engaged in a duel when Sidious commanded Silus to assassinate Maul and assume his position as the Dark Lord's apprentice. Although Silus was skilled, and despite a dampening field hindering Maul's lightsaber use, the Sith apprentice ultimately prevailed and decapitated him.
