Sam Maggs seems to be a fan of really obscure details and alien species from the “Star Wars” universe. For one, the defecting Stormtrooper, Fret, is a Keshiri, which first appeared in John Jackson Miller’s “Lost Tribe of the Sith” stories. They were pink or purple near-humans and considered incredibly attractive to humans. Or, in this case, Dathomiris. The other major new character in the book was identified as a bird-like Omwati. Fans of the old expanded universe will recognize them from Kevin J. Anderson’s work and the character Qwi Xux, who used to be Wedge Antilles’ girlfriend. Chuck Wendig canonized them in passing in the new canon, but Maggs gives them the spotlight in this book.
The prison where the data is being held is Murkhana, which was a prison James Luceno created for the book “Tarkin.”
One of the most interesting aspects of the book is that we are able to finally get some more details about The Fifth Brother and his pivot to the dark side and the Inquisitorius. He first appeared in “Star Wars Rebels” and made the jump to the “Obi-Wan Kenobi” TV show. This book reveals that he’s from the planet Artemesium and was taken from his family there by the Jedi at an early age. He watched the Jedi collude with the senate as the senate voted to strip Artemsium for resources, causing the start of his disillusion with the Jedi.
