Ones that aren't on the tribute thread. I found one backdrop that was called the forgotten temple and I thought that was Zelda but I wanted to be sure

I own these if it helps (not sure where the tribute thread is atm) Whats the exact name of the item you are referring to? [Item=mysterious Ocarina] They are older and may be known on the thread idk.

Forgotten Temple Candles :o

that might be a genshin tribute, I'm not sure you could always ask that user.
