Darth Igrol, a male Sith pureblood, rose to become a Dark Lord of the Sith and held a position on the Dark Council of the reconstituted Sith Empire. His rise to this twelve-member governing body occurred sometime in the period between 3984 and 3974 BBY. By 3954 BBY, only Darth Xedrix had a longer tenure on the Council than he did.
Instead of residing in the Empire's capital on Dromund Kaas, Igrol lived in a lavish estate located on the planet Dromund Fels. However, in 3950 BBY, he was summoned to the Imperial Citadel along with eight other Dark Council members for a meeting with the Sith Emperor. The Emperor swiftly killed these Dark Councilors only a few hours before his Imperial Guard purged the remaining three, including Darth Nyriss, because five of the Councilors were involved in a conspiracy against the Emperor.
The first mention of Darth Igrol occurred in The Old Republic: Revan, a 2011 novel penned by Drew Karpyshyn.
