I am writing a book for it! It will include a page for each minor, two pages for each major, several spreads, and some information about scrying. The 79th card in the deck is the back image on both sides, a solid black box with a double Fibonacci square on either side of a staring eye (The last image on the poster). When all is said and done, the black portions of the back design will be mirror-like black surfaces. On both sides of the card.

The Sigil Arcanum is sort of a pet project of mine, but it's been fun to work on, now I just need to get it made.

@tarotbyfergus is a friend of mine, he's a tarot and palm reader at the metaphysical shop I work at. Also, the Kickstarter will hopefully be online in the next couple weeks, and will go live in March or April. More to come on that!
