A children’s book based on sci-fi shooter Destiny, created by the artists and writers at Bungie, will be published and available at major booksellers very soon.

Destiny got a new surge of life this week with the release of Rise of Iron, Destiny’s fall expansion and official kickoff to the game’s Year 3. Things are at a fever pitch for fans right now as they dive into the new content and prepare for the sci-fi shooter’s latest raid. Destiny continues to have a dedicated fan base, and it looks like Bungie is reaching out further than people’s consoles to bring the universe of Destiny to life.

For dedicated fans, D is for Destiny may look like something they have seen before—and that’s because it is. The book, which was completely illustrated and written by the artists and writers at Bungie, was originally an internal Christmas gift given only to Bungie employees in December 2013.

From the world of Destiny, this rhyming alphabet book takes young readers on a voyage through a universe of adventure. From Four-Armed Fallen to the Mysteries of Mercury and the Moon, D is for Destiny makes exploring the far reaches of the solar system as easy as A, B, C.

As Bungie tells it, friends of employees starting seeing the book and asked when they could buy a copy as well. In 2014, Bungie self-published D is for Destiny and sold it on the company’s own online store. It is still available to purchase on BungieStore.com.

D is for Destiny uses words like Fallen, Cabal, and “Be Brave” to walk through the alphabet. And rhyming stanzas like this one for the Fallen:

Meanwhile, Destiny: Rise of Iron is available now on PS4 and Xbox One.

Four-armed Fallen sail the Frontier.

Pirates in space, they live with no fear.

Their Houses are many, spread far and wide,

But when heroes take chase, they run off and hide.
