Baze and Chirrut from Rogue One were Guardians of the Whills. They weren’t Whills themselves but at least it’s been mentioned in a movie now along with Kyber Crystals. Maybe Snoke is a Whill. I’m sure Luke learned a lot from those books in the cave on that island
Disney is infusing a lot of fantasy elements in a franchise that desperately needed a break from the sci fi bullshit of the vong and midi chlorians…good
I loved that Maz reiterated Yoda’s description of the Force without mentioning midichlorians.
Maz is also the same character who glossed over the magical reappearance of a lightsaber that would have disintegrated in a gas giant (Bespin) within seconds of falling into it at the climax of ESB, so her word is hardly worth a Gungan’s foot.
