He is the evil ruler of the Shadowlands beyond the Barrier Mountains, north of Deltora and the supreme leader of the Shadow Army. He is the main antagonist of the Deltora Quest series and is shown to be a very powerful sorcerer. He resided in the Shadowlands and made attempts to rule Deltora throughout the series. He is shown to be a very clever planner and creates many plans to foil even those who appear to defeat him at first. His most loyal servants are the seven Ak-Baba, huge, monstrous vulture-like birds that are very strong, and lives a thousand years. He is, in short, a megalomaniac, being convinced that all creatures should obey him. The Shadow Lord apparently goes by a policy that if he can't have something, he will simply destroy it, evident by deciding to just destroy Deltora with the Grey Tide when the Four Sisters failed. He is also very sadistic, deriving pleasure from tormenting Lief mentally. The Shadow Lord cares nothing about his subordinates, viewing them as simple pawns. An exception to this may be the Ak-Baba, if for their strength and loyalty if no other reason.
