Two versions of this spell existed: The one had been employed by arcane spellcasters in the Old Empires of Mulhorand, Unther and Chessenta as essential to practice their separate system of magic introduced after the secession of Thay (though some of them also knew the northern counter-part, read magic, giving access to spells from outside their domain).
The second and much younger version was a rare spell created by Random Riellor from Halruaa and allowed wizards from outside the closed ranks of southern magicians to read their encoded arcane writings.
Random only shared this spell with those whom he believed could further his research.
