It was magic and just disappeared and people are used to magic so… yeah shit’s gone, yo
That makes a lot of sense, just like with the secret stones, which would have probably been better translated as sacred stones, as they are not secret.
…and it sounds way cooler IMHO. “Secret Stone” sounds like something a preteen would use in a short story about a superhero they just made up, or maybe a placeholder name that they never bothered to change.
I’m just going to pretend that they ARE called Sacred Stones and Hyruleans just pronounce it a bit differently.
