Vialco

Vialco was an apprentice inquisitor during the events of the young Jedi, Fable Astin, being trained by Adalric Brandl. Vialco haunted Fable's dreams and tried to lure her to the Dark Side, but was unintentionally killed by Fable because of an illusion created by Brandl. However, the reports of Vialco's death were premature. Contrary to the image he displayed to people, Vialco was a master of the dark side, and was able to transfer his spirit into a healthy clone body, a technique which he had stolen from the Emperor's private holocron.
