Eligor, also known as Eligos, Abigor or the Great Duke of Hades, is the 15th demonic spirit of the Ars Goetia and a fallen angel. He governs over 60 legions of spirits. He is a great duke and appears in the form of a goodly knight carrying a lance, pennon (flag) and a scepter (a serpent to Aleister Crowley). Alternatively he is depicted as a ghostly specter, sometimes riding a semi-skeletal (sometimes winged) horse, or the Steed of Abigor. This is a minion of Hell itself, and was a gift from Beelzebub. It was created from the remains of one of the horses of the Garden of Eden.
He can discover hidden objects, kindles love and lust, knows the future of wars and how soldiers should meet, along with procuring the favor of lords, knights and other important people. He is apt for divination and the performance of spells to strategize one's life. In modern military terms he is a high-ranking General who not only understands the subtle strategies of warfare, but also has the ability to foresee an enemy's position and tactics ahead of the battle itself.
He marshals armies and causes war. He teaches leaders how to win the loyalty of soldiers. According to the Grand Grimoire, he is a direct subordinate of Fleurety.
Eligor is found patrolling the Ginza underground mall. After entering the Assembly of Nihilo proper, he shows up to fight the Demi-fiend twice; he will appear once more if the Demi-fiend opens a specific chest, and summons a different group of demons to assist him each time. Despite Eligor's boss status, he can be fused before he is fought. Eligor later randomly appears in random encounters in Asakusa and the Labyrinth of Amala.
