Even its name is a secret. Some say it comes from the Sodality of Vryn, which identifies thirteen currents of magic and gives each a letter designation - M is the 13th and most powerful.

Whatever the source of its name, Book M is one of the rarest and most sought-after grimoires. It's whispered to contain otherwise unknown spells, incantations, rituals, charms, hexes, and more. Plus potions, amulets, bezoars, spiritstones, and madstones, as well as other physical ephemera. Within its pages a vislae might even discover previously unknown artifacts to aid in the pursuit of the secrets of reality.
