Unidentified masked Sith

A Force-sensitive humanoid Sith was killed in battle by the former Sith known as the Ronin, who hunted members of the Sith following their failed rebellion against the Jedi clans. The Ronin later met the Jedi known as Shogun in a hot spring and told them they had killed many individuals, remembering the humanoid Sith and others he had killed. The Sith wielded a red lightsaber and wore a mask covering most of their head and face, exposing only their eyes and ears.
