Who Goes there?
In this Zelda: Tears of the Kingdom side adventure guide, we'll give you the complete solution for the side adventure quest: Who Goes there?
To unlock this side adventure quest, all you have to do is talk to Jerrin, the one who is sweeping up in front of a wall that appears to have a large hole in it, in the Emergency Shelter located in the Lookout Standing.
She'll tell you that she hears a frightening voice coming from this hole. At the end of your discussion, you'll unlock the side quest: Who Goes there? Enter this hole to discover a Royal Hidden Passage and break the stones (using the appropriate weapon) to unlock the path. Head for the stone on the right and destroy it to find the Forbidden Horned Statue.
Talk to the statue to trigger a cinematic in which the statue appears to have stolen a heart from you. This will also trigger the side quest: A Deal with the Statue.
At the end of the discussion with the Forbidden Horned Statue, meet Jerrin in front of the wall to reassure her. As a reward, you'll receive 20 Red Rupees. This concludes the side quest: Who Goes there?
