Zelda secret sound

[rick31]

So I’m playing Skrim on switch when on the go as Oblivion remastered has got me hooked again.

I did some amiibo powers and have the Master sword and tunic equipped. I’m right at the beginning of the game and as I’m walking to Halted Stream Camp from Whiterun I got the secret found sound effect from Zelda.

There seems to be nothing around me. What is this?

Searched google and this sub and just came up with junk results unrelated
