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. Others say the title refers to the original writer of the book, while still others believe it stands for mystery, or—perhaps most simply and obviously—magic.

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 artifacts of great power.

New forte. New long-form magic. New character and house secrets. And more guidelines and advice for making magic even easier—and more magical.
