In this book, you will delve deep into the mysterious forces of the cosmos, as well as how they are being expressed through the Star Signs, the constellations that illuminate the darkness of the night sky. Those born under the light of the Star Signs are inclined to be in attunement with their cosmic essence, perpetually altering the course of their lives ever since the moment of their birth. You will also learn of how the planes of existence influence our world, in conjunction with the lore about the cosmic phenomena that occur because of this influence. Lastly, you will become adept in the art of cartomancy, capable of auguring the future, past and present through the use of the mystifying Deck of Fates.
