HIGHLANDER: THE FINAL DIMENSION (apparently also called HIGHLANDER III: THE SORCERER) arrived in late 1994 in the U.K., early 1995 in the U.S. It was only about three years after THE QUICKENING and already the producers were like, “I don’t know what you mean, ‘Planet Zeist.’ That’s not a thing that was ever mentioned in our movies.” And they made a new HIGHLANDER sequel that didn’t acknowledge any of that stuff – “a stand-alone alternate sequel to the original film,” as Wikipedia puts it. Of course, it takes place in 1994, so in my opinion it is for sure just an adventure Connor MacLeod had shortly before the ozone layer got real bad and he transitioned into the shield-building
industry and then years later was at an opera that reminded him he was from Planet Zeist.
But before they take us to Connor in the ’90s they fill in a piece of backstory that was skipped before. Turns out after his mentor Ramirez and then his wife Heather died back on the Highlands he wandered the world “searching for answers” until he “came to Japan, to the mountains of Niri and the cave of the sorcerer Nakano.” We see Nakano (motherfuckin Mako, CONAN THE BARBARIAN) forging Connor’s familiar sword. A ha*. Prequel.
