Since time immemorial, mortals have been connected to the enigmatic Astral Plane. Dreaming of the swirling, ever changing plane of existence, infinite astral constellations of eldritch origin dotting the skies of the plane and soaring in and out of sight.
Eventually, through vigorous study or just pure curiosity, mortals copied the patterns in the constellations into tomes as single Arcane Sigils and discovered that a tome inscribed with these Sigils emanated immense Arcane power.
After studying the tomes, ancient denizens of Aevonhold discovered that when an Arcane Sigil is memorized, the Sigil can be converted into a physical Arcane reaction. After realizing this, many ancient mortals with the Gift began to inscribe tomes with Sigils they had seen when dreaming of the Astral Plane themselves.
It was discovered a short time after that the astral constellations when turned into Sigils would elicit many different reactions or, spells. There are an infinite number of Arcane Sigils for any type of magic or spell and many more are to be discovered.
