Oberion
Oberion (also Oberyon, Oberycom, and Ebrion) is a spirit derived from the fairy Oberon, who for a time appeared in grimoires himself. In many of Oberion's appearances in grimoires, his counseling spirits are usually Storax, Carmelyon, Caberyon, and Seberyon.
According to Liber Officiorum Spirituum, his wife is named Mycob.
Appearance
The Book of Oberon describes him as simply "a king with a crown on his head."
The Book of Magic, with Instructions for Invoking Spirits, etc. depicts him as a floating, turban-wearing spirit with what seems to be a cloak-like piece of clothing that parts in the middle and ends in three curly tips pointing in different directions. Above this is the other drawing which depicts him in a way that's more in line with the previous descriptions, that being the form of a king wearing a crown, but this particular drawing has him raising a sword in his right hand with his left resting on his belt in addition to this.
The Astrologer of the Nineteenth Century adopts and adapts the turban-wearing depiction, saying he "appears in great pomp and terror, generally in the form of a scaly monster, the face of a woman, and a royal crown upon his head."
The Grimoire of Arthur Gauntlet describes him as coming "in the likeness of a Beautiful man like a Soldier personally in the air or in a glass."
Abilities
Oberion is said to teach medicine and the natures of stones, herbs, trees, and metals, in addition to being able to turn people invisible, tell the past and future, show where and how to get treasure. If bound by a magician, he can carry treasure out from the sea.
The geomantic lot book The Royal Book of Fate gives the twenty-first figure to this spirit, and its corresponding icon is an open book.
Invocation
Oberion is one of three spirits (the others were "Andrea Malchus" and "Inchubus") said to have been raised up by the parson of Lesingham and Sir John of Leiston in Norfolk, England in 1528.
