Regional Phenomena - End
In this walkthrough for The Legend of Zelda: Tears of the Kingdom, we'll give you the complete tutorial for the main quest: Regional Phenomena - End.
After completing the main quest: The Lighting Temple and defeating the Scourge of The Lighting Temple: Queen Gibdo, feel free to talk to the characters located in Gerudo Town to unlock side quests or missions including: The Heroines' Secret and more.
Once you've completed all the regional surveys, which means you've visited all 4 regions: Rito Village, Goron Village, Zora's Domain and Gerudo Town, head to the Lookout Standing to chat with Pru'ha.
You'll find Pru'ha at the top of the Lookout Standing. She's standing in front of her telescope at the top. Use the stairs and ladders to climb to the top.
When you reach the top, Pru'ha will congratulate you on your work. Suddenly, the sky turns red and Pru'ha points out that Zelda is standing on top of Hyrule Castle.
Pru'ha will then ask you to head for Hyrule's Floating Castle, since you're the only one with the ability to get there.
And so the main quest: Regional Phenomena - End comes to an end, making way for your next main quest in Zelda: Tears of the Kingdom: Crisis at Hyrule Castle - Part 2.
