Wayfinders were ancient pieces of technology created by both the Jedi and Sith as a means of navigating challenging stretches of space. They were created through the study of the brains of purrgil, space-faring megafauna who could travel through hyperspace by biological means. Both religions chose to imbue their wayfinders with the Force, requiring a Force-user to activate the wayfinder, so that secrecy and safety was ensured. Jedi star compasses were designed similarly to wayfinders.

The Eye of Webbish Bog was a spider-like being that existed on the planet Mustafar. It was locked in symbiosis with a blind giant, living within a lake near the Corvax Fen. It encountered the Sith Lord Darth Vader during the Galactic Civil War when Vader was punished by Emperor Palpatine for his past failures. While Vader tried to survive and fight against Ochi of Bestoon, a Sith assassin send by his Sith Master, Vader awakened the Eye through the Force and went to meet him, an encounter in which the Eye attacked Vader with questions and inquiries about his past before giving him a Sith wayfinder to find the hidden Sith world of Exegol.

Years after Vader’s death, the Eye of Webbish Bog met with Supreme Leader Kylo Ren from the First Order, who was Vader’s grandson, during the war between the First Order and the Resistance. After slaughtering the Alazmec of Winsit with his forces, Ren encountered the Eye, who claimed to have been tasked with guardianship of Vader’s wayfinder by Vader himself, and directed the Supreme Leader to the artifact‘s location after considering him worthy of having earned the wayfinder for destroying its protectors.
