Publisher's blurb: If you own Book M or The Nightside, you can easily combine their cards for spells, ephemera, incantations, and so on with those from The Black Cube, putting them all in one place. But what about the long-form and minor magics contained within those products? Wouldn’t it be handy to gather all of those together into one source? This...gives you exactly that: a complete encyclopedia of every minor magic, long-form magic, and secret—all in one place for easy searching and reference. It will make your Invisible Sun game experience even better!
