The Demon Demoriel is a Demon among the 31 Aerial Spirits of Solomon.
Demoriel is the emperor of the north, served by 400 great dukes, 600 lesser dukes, and 7,000,008,000,009,000,001 ministering spirits. The Demon Demoriel is one of four Demons named in the Ars Theurgia in connection with the cardinal directions.
According to this text, Demoriel is the primary Emperor of the North, and he rules in this point of the compass with a retinue of four hundred great dukes and six hundred lesser dukes.
