The Shiekah are super interesting in Zelda lore. It's hypothesized that they are re-deads who have devoted themselves to protecting Hylian graves (e.g. where the sun song is stored). This sort of practice is reinforced in BotW where they suspend their animation to give spirit orbs to Link. Also, there was this idea that in the trailer for BotW2, Ganondorf was captured and his life force was being siphoned to power the robotics in Hyrule and that's the primary reason he could corrupt all the robits. It was as if the Shiekah had forced him to become suspended and tortured at the same time.

It would have been amazing to see some resolution to the shadow temple/civil war in the wake of getting the shadow medallion. Clearly it would be difficult to do as the first thing you ever create for the N64, but still. Maybe if Ganondorf had some general in his castle who was the person who started the war and it was revealed that he was the Hylian royalty who oversaw the tortures in the shadow temple.
