Seere

One of the seventy-two demons of the Goetia.  Seere's name is left out of both Wierus's Pseudomonarchia Daemonum and Scot's Discoverie of Witchcraft, both texts that otherwise include the magority of t he Goetic demons.  In the Goetia, Seere is said to hold the rank of prince with twenty-six legions under his command.  He is tied to the demon Amaimon, who rules as the infernal king of the east.  When he manifests, Seere takes the form of a beautiful man.  He rides upon a horse with wings.  He is a demon of transportation, fetching things from any corner of the globe.  He is said to have the power to pass over the whole globe in a twinkling of an eye.  He can also reveal thieves and expose hidden treasures.  He further seems able to alter the movement of time, as he is said to bring all things suddenly to pass.  According to the Goetia of Dr. Rudd, he is constrained by the angel Tabamiah.  He can be found in the Welsh Book of Incantations under the spelling Seer.  See also AMAIMON, BOOK OF INCANTATIONS, GOETIA, RUDD, SCOT, WIERUS.

Seere/Sear/Seir is the Seventieth Spirit who is a Might and Powerful Prince, who is under AMAYMON, the King of the East.  Seere appears in the form of a beautiful and angelic male, who rides upon a Winged Horse.  He is a powerful angel who brings the sorcerer's Will to flesh quickly, and will disappear until you are ready for him to return.  Being a Luciferic Spirit, Seere resides in the Air and may pass over the earth in a blink of the eye.  He initiates the self toward the higher spheres of Light and the Sun, from which one rides the Aethyr unto a higher articulation of being through the Familiar.  Seere governs 26 Legions of Spirits, and is of a Good Nature.
