Dictionnaire Infernal – Collin de Plancy (1863) (paraphrased)
Abigor presents himself as a horseman carrying a lance, a standard, or a scepter. He commands sixty legions & is a grand duke of hell. He knows of the secrets of warfare, of the future, and can instruct leaders of the ways to earn their soldiers’ respect.
