He was of the order of Virtues. According to the Grand Grimoire, he is a direct subordinate of Lucifuge.
"One of the 72 demons of the Goetia. He is a Grand Duke that rules the eastern zone of Hell. He rides various grotesque creatures, like crocodiles, and appears as an old sage with a hawk on his arm. He grants words of wisdom to those who summon him and will bring back fugitives who escaped the summoner. He also causes destruction through earthquakes."
