Unidentified sacred Jedi text

A sacred Jedi text of the Jedi Order was a book of wisdom that dated back to the Order's dawn. Between 3 ABY and 4 ABY, Jedi-in-training Luke Skywalker visited the Living Sea on the planet Gazian, a living vergence in the Force, in search of knowledge of the Jedi. After speaking with an imprint of Jedi Master Elzar Mann's mind, Skywalker received the text from a skeleton of a dead Jedi. Sometime later, Skywalker had the book aboard Amilyn Holdo's starship, the Skyfarer, when he, Holdo, Chewbacca, Lando Calrissian, and Leia Organa were stranded in No-Space. The Skyfarer was left aboard the Great Hall of the Nihil, the former main base of the Nihil, and as the rebels were with the Colony of Kezarat, Skywalker expressed his concerns to Organa about losing the book as he felt it was irreplaceable and that he would not be able to move forward in his training. Meanwhile, at the Skyfarer, Killdroids broke into the ship so they could retrieve a Path engine that had been installed on the ship, with one of the droids throwing the text out of the ship and it hung on the edge of the Great Hall.

By 34 ABY, Skywalker, now a Jedi Master, had stored the text alongside others in the tree library on the planet Ahch-To. Rey, Skywalker's Padawan, later took the texts with her aboard the Millennium Falcon as she left the planet.
