Dolac Legasi was a male assassin of the Human species, prominent during the era of the Galactic Civil War.
A skilled assassin, Dolac Legasi at one point trained Roden Venthrall as his apprentice. Eventually, Legasi's activities led to his capture by the forces of the Galactic Empire. He received a sentence of life imprisonment within the Imperial Prison located on the planet of Dathomir. The order for his imprisonment came directly from Emperor Palpatine, although the underlying reason remained unclear. Legasi speculated that Palpatine might have perceived him as a potential future rival for control of the Empire. In the year 1 ABY, Dolac Legasi played a role in assisting Imperial officer Mozo Bondog in solving the mystery surrounding the disappearances of inmates. He instructed an unknown individual to retrieve one of the inmates that had mysteriously reappeared. Subsequently, he tasked the same spacer with the acquisition of a shadow shard. This shard was, in reality, a fragment of a Sith holocron, intended to guide the individual to the place of shadows and the recovery of the shadow stone. After examining the shard, Dolac revealed the presence of an ancient evil on Dathomir: a Sith entity capable of dominating the minds of others. This Sith was identified as the culprit behind the missing prisoners, having seized control of their minds, as well as the Imperial prison guards, who erased any trace of their actions, ensuring no one remembered what had occurred. Legasi fabricated a story about being approached by this Sith, who sought his allegiance, which he supposedly refused. He also claimed to be too powerful to be controlled, leading the Sith to plot his demise. Consequently, he orchestrated the elimination of the Sith by providing the individual with the coordinates of their location. The spacer engaged and defeated the Dark Jedi Master along with three Nightsisters. As a reward for this deed, Legasi bestowed upon the individual 1,800 credits.
Dolac Legasi appeared as a non-player character within the 2003 video game Star Wars Galaxies. This game was a massively multiplayer online roleplaying game developed by Sony Online Entertainment and published by LucasArts. The game's servers were shut down on December 15, 2011.
While never explicitly stated, it was strongly implied that Dolac Legasi possessed Force-sensitive abilities. This implication stems from his imprisonment on Dathomir by Emperor Palpatine, possibly due to the threat he posed. Furthermore, he asserted his resistance to the Sith's mind control and the Sith's desire for his allegiance upon recognizing his strength.
