The Legend of Zelda
In The Legend of Zelda, the Underworld can be accessed throughout various entrances scattered all over Hyrule that, upon entering, actually serve as the game's dungeons. In total, there are nine underworld entrances around the kingdom that Link must enter in order to retrieve a shard of the Triforce of Wisdom.
The Adventure of Link
Although the Underworld is not visited in The Adventure of Link, it is mentioned in the game's prologue where it says that Ganon's minions were calling up new monsters from the Underworld to work towards the revival of the evil wizard, implying that the Underworld is where the monsters actually originate.
- In Japan, the Underground and the Underworld are two different places. The Underground from The Legend of Zelda is named 地下 (Underground), literally referring to the location of the Labyrinths which are below the earth. The Underworld mentioned in the The Adventure of Link manual is named 魔界 (Demon World), a term which is later used in Ocarina of Time and describes what happened to the Sacred Realm once Ganondorf obtained the Triforce of Power.
- "At that time, Ganon's underlings were calling up new allies from the Underworld, and were beginning to work devilishly towards the revival of Ganon" (The Adventure of Link manual, pg. 12)
- "When Impa gave Link the order to destroy Ganon she also told him of the history of the land of Hyrule, and the layout of the nine underground secret labyrinths." (The Legend of Zelda manual, pg. 5)
- "The entrances to the underground labyrinths are hidden all over the place. [...] And once Link's found a labyrinth, he'll always get an item of treasure." (The Legend of Zelda manual, pg. 7)
