Null's Body is the eighth and final Dungeon of Echoes of Wisdom.
Entrance to the Dungeon[]
Null's Body can only be accessed at the end of the "Rescuing the Hero Link" quest line, which itself can only be unlocked once the first seven dungeons are all completed.
After making her way through the Stilled Ancient Ruins and rescuing Link from Tekom, Zelda and Link follow the Prime Energy into a dark, cloudy sphere at the center of the Still World.
[]
As its title suggests, Null's Body takes place within the insides of Null, a primordial being that has been trying to destroy Hyrule through a series of rifts, all so it can break free from its prison and consume all of existence. Null has been consuming Tri's friends; as such, the purple walls of Null's Body are lined with digested Tris in its cells.
To get to Null's core, Zelda and Link must work together to solve puzzles and battle the various echoed enemies that Null summons to impede their progress. Zelda can use Bind to clear paths for Link from separate rooms, while Link can act as the muscle by warding off monsters to keep Zelda safe.
Eventually, Zelda and Link will reach a straight path leading into a dark abyss: Null's core. Link nods at the princess, and the two jump in to face Null together.
Trivia[]
- The premise of entering a living creature seems to be inspire by Inside Jabu-Jabu's Belly from Ocarina of Time.
