The Tower of the Sun is a large island with hollow interior.[]
The Tower of the Sun is a very tall island, with small cliffs jutting out in the interior. These can be used to scale it and reach the top, which is the first area where the player encounters water. The Tower of the Sun contains a Sacred Flame, which you will need to progress. The tower is linked to a path which connects it to Windmill Plains and the Temple of the Desert Fortress.
