Zelda: Tears of the Kingdom Fifth Sage Location - Find The Ruins From The Age Of Legends

gamespot.com:

The Legend of Zelda: Tears of the Kingdom Fifth Sage is one of the game's main quests. Why bother talking about it? Well, it's because there's hardly any clue, and you might get frustrated trying to look for the objective. Don't worry, because our guide will help you find the Fifth Sage location in Zelda: Tears of the Kingdom. Likewise, please be reminded that this article contains spoilers.

You'll get the Zelda: Tears of the Kingdom Fifth Sage quest after beating Phantom Ganon in Hyrule Castle. As the group discusses the recent turn of events, Purah tells you that there might be a Fifth Sage somewhere. Your only clue is to "find the ruins from the age of legends."

There are a lot of ruins in the game, and most of them match that vague description. If you've been exploring as much as you can, there's a chance that you'd think every major landmark fits the bill. However, the location is actually the Ring Ruins in Kakariko. In fact, it's the fifth and final stone tablet, which you'd be familiar with if you've already completed A Trip Through History.

To reach it, use your traversal abilities to get to the central section in the area (the one that you couldn't go to earlier since the NPC, Calip, was warning you). You should be able to use your Ascend ability to reach the small room. Take a photo using the Purah Pad, then return to Paya and Tauro down below to share your findings.

Note: As of the time of this writing, we can't confirm if A Trip Through History must be completed beforehand just to trigger the quest step. We were already done with that side quest by the time we got the Fifth Sage objective.

The next steps of the Zelda: Tears of the Kingdom Fifth Sage quest turn into a very long trek:
