Ever since she first appeared on-screen in The Force Awakens, fans have been clamoring to know where the force-sensitive Rey came from and who within the larger cannon she was possibly related to. The Last Jedi tried to say she was simply the daughter of a couple of nobodies, but Rise of Skywalker quickly changed that twist and made her the granddaughter of Emperor Palpatine.

While it was a somewhat divisive choice and probably came out of nowhere for some, it may not have been that much of a surprise for Star Wars fans who had read the forgotten non-cannon book series The Jedi Prince.

Set about a year after the events of Return of the Jedi, The Jedi Prince series is a series of six young adult chapter books that follows Luke and his friends as they try to stop the rise of a new empire led by the purported son of Palpatine, Triocolus and also deal with Jabba the Hutt’s father, Zorba the Hutt.

Along the way, Luke discovers the so-called Lost City of the Jedi and in it, a young man with a mysterious origin, much like Rey, named Ken, who has lived with droids his whole life. Over the course of the book series, Ken joins Luke on his adventures in an attempt to find out where he comes from. Much like fans who speculated Rey was related to Obi-wan Kenobi, Ken himself guesses Obi-wan may be his grandfather, but we soon learn that Ken is, in fact, the son of Triclops, the true three-eyed of son Emperor  Palpatine who his father shunned for being a mutant(not a clone like Rey’s father in the sequel trilogy), and the Jedi Kendalina.

While the Jedi Prince series is largely forgotten and no longer considered canon, it did happen to predict the Rey/Palpatine connection before the sequel trilogy. So is it a case of parallel thinking, or did the writers of Rise of Skywalker pick and choose plot points for a nearly 30-year-old book series? We may never know for sure, but at least we can remember The Jedi Prince for solving the mystery of Rey’s parents before it was even a mystery.
