Gregorovic, also known as The Faceless One, is the general of Sliske's army in the Heart of Gielinor. Gregorovic was a fatally ill human of the Fourth Age, who was desperate to avoid death. In the hope of prolonging his life, he captured some of the few Cywir elves living in Gielinor and employed torturous experiments to unsuccessfully extract the secret of their long lifespan. During the fight with Gregorovic, Akrisae the Doomed with one million life points may rarely appear and start attacking the player. The conditions required for this to happen are unknown.
