Darunia is a major character in The Legend of Zelda: Ocarina of Time. Probably my favorite Goron of the series, though they all kind of look the same LOL.

He’s the leader of the Goron people. So he asks Link to help with that whole thing going on in Dodongo’s Cavern.

For which Link gets the Goron’s Ruby for his hard work.

And sure enough, he shows up in the Fire Temple the same time you do.

And becomes the new Sage of Fire which makes pretty darn good sense.

And he gives you the Fire Medallion when you’re done.
