Sky keep is such a special dungeon because besides the obvious "shift the entire dungeon around as part of the puzzle" which would later be adapted by botw's divine beasts, the dungeon is like a last hurrah of the entire game.
You start out, get the dungeon map, Fi marks the triforce locations and it's go time. You walk over to the pedestal and move the first room over.
You walk in and familiar music stats to play. You're in Skyview temple again. Puzzles with the beetle and the slingshot, rope swinging, parts with the gustbellows like in the great tree, it's beautiful. Once you've gotten through it again, you open up a shortcut, showing that once again you've conquered skykeep.
You go into the next room and the music almost flawlessly transitions as your next puzzle awaits you, but which puzzle is it? That's up to you.
There's the trial of courage, having you face off against multiple opponents in the basement of the ancient cistern, the fight against LD-03D Dreadfuse, a revamped Scervo fight, there's a puzzle with bomb bowling in the earth temple, a moldorm fight and so much more.
and the Triforce? You go to collect it and you return to the silent realms, a place of anxiety for a lot of players, but this time...
It's peaceful. you won.
Sky keep is skyward sword, it's a temple about seeing your growth, and how you've become a hero since the beginning of your journey, just like link.
