Have you visited the Sacred Valley? If you stare at it from a very high place, you’ll notice there’s a giant ball of fire in the forest across the river!
You can seek it if you want! If you’re coming from the Old Docks after getting a Trixen Trip, just head west towards the lake, and then walk to the ruined bridge! You’ll have to cross it, but don’t worry, its perfectly safe, in order to reach the beach! Now if you look closely into the forest you’ll find an almost hidden path to the shrine!
Apparently the entrance to the shrine is closed to everyone but “the faithful”, according to the fox statues at the entrance! But if you listen closely, you’ll find out a hint on how to get through the barrier! It takes a little bit of walking around the valley and solving puzzles, but its fun and different!
