While Wright and Left try to prove their identities, the Hyrule Castle Town rift gets much bigger, but Tri finds an entrance into it.

Reach Hyrule Castle

Go north and go up the stairs. Then go south to exit the room.

Go south, then east, and jump across the small islands. Defeat the monsters on the other side. Don't go into the shop, because there are just two Moblins and a ReDead inside.

Instead, make your way north and follow the path. When you reach the fountain, defeat the two dark monsters. Then go north to where there is water. Go west and check on the waypoint to add it to your map. Then bind to the treasure chest and pull on it, then open it to get 7 portions of radiant butter.

Before you move on, use echoes to get on top of the wall near the waypoint. For example, a table and a Platboom. Then use echoes to go to the small island on the left. For example, a table and a Flying Tile. Then open the chest to get 20 rupees.

Go back to the waypoint, then go north into the sideways water and hold B to go to the surface. Go east and walk on the sideways trees to reach the rocky ledge to the east. Go down and get the 20 rupees to the east. Then use echoes, such as a table and a Platboom, to go back up to the water above you.

Hold B to go to the surface of the water. Then carefully go through the different water areas using water blocks, and go north. You reach the entrance of the castle. Go inside. There will be a cutscene. You are now in Hyrule Castle.
