Gharlane of Eddore was a character in the ret-con version of Doc Smith's Lensman novels, Master Number Two of the Innermost Circle of the All-Highest of Eddore. Gharlane was the Eddorian responsible for inhibiting/halting the Arisian-directed progress on the planets Sol III, Velantia III, Rigel IV, and Palain VII. While his modes of operation on Rigel IV and Palain VII were never described, his work on Velantia III was based on the introduction of the Overlords of Delgon on Velantia II
On Sol III/Tellus/Earth, Gharlane usually operated by activating various humans who were positioned to interfere directly with the progress of civilization. He acted as Lo Sung of Uighar, the leader of one of the nations in conflict with Atlantis, and initiated the nuclear exchange which destroyed Atlantis. He activated the Roman Emperor Nero. As well as Lo Sung and Nero, in the encounter between Drounli/Bergenholm and Gharlane at the beginning of "First Lensman" Drounli names Gharlane as the activator of these humans: Mithridates of Pontus, Sulla, Marius, Hannibal of Carthage, Alcixerxes of Greece, Menocoptes of Egypt, Genghis Khan, Attila, the Kaiser, Mussolini, Hitler and the Tyrant of Asia. Smith implies that he was active during the period of the three World Wars, and that when he left Earth after the Third World War, he had created the Adepts of North Polar Jupiter to assure the continued inhibition of the humanity of Sol III. After his return to the Sol system centuries later, activating the human form of flesh known as Gray Roger, he was the Chief Devil of the Adepts of North Polar Jupiter and an alumnus of Harvard.
Gharlane attempted to destroy the Arisian-activated human form known as Nels Bergenholm, but was blocked by Drounli the Moulder, one of the four Arisians comprising the fusion known to Civilisation as Mentor of Arisia, in the first overt action taken by the Arisians in their aeon-long conflict with Eddore.
Gharlane passed into the next plane of existence after a mental battle with Kimball Kinnison and Mentor of Arisia aboard the Thrallian flagship during the Battle of Klovia, while activating the Thrallian human form of flesh known as Prime Minister Fossten.
