Avrak Villachor, a Black Sun Sector Chief of the Human male persuasion, resided on the planet of Wukkar. He was famous for hosting the Festival of Four Honorings at his residence, Marblewood Estate, situated in Iltarr City. This chief was entrusted with the responsibility of safeguarding Prince Xizor's confidential blackmail documents inside his vault. These files were subsequently pilfered by Han Solo's crew, an event that preceded the death of Qazadi, a Black Sun vigo, within his domicile. Consequently, Villachor, aware that Black Sun would exact retribution, requested sanctuary from the Galactic Empire.
