The Lost Underworld is a location in EarthBound. It is reached by going through a hole in Lumine Hall. The Lost Underworld is tremendous in size and seems untouched by time and modern innovation. It is home to dinosaur species and Tendas. Deep into the Lost Underworld, is Fire Spring, the last and eighth Your Sanctuary location.

The Lost Underworld first appears after defeating the Electro Specter and gaining the melody of Lumine Hall. It is used as the only exit from Lumine Hall. The party lands in the south east area. When Ness and his friends first go to the Lost Underworld, the player can notice that the sprites of the characters are noticeably smaller, emphasizing the largeness of the area. Inside, Ness will find dinosaurs, showing that the area is almost unknown and untouched by time. There are also geysers that shoot out blue or red water, healing HP and Status Ailments respectively. Talking to the Tenda villagers here will show that the dinosaurs are actually in "cages", although it appears that the Tendas are in the cages. Ness and his friends must reach the end to get to Fire Spring and record the eighth melody.

Role in EarthBound

After recording the melody of Lumine Hall, the team jump into a hole dropping them deep into the Lost Underworld. They find the land is untouched by modern time with dinosaurs running rampart. They find another village inhabited by Tendas and are let in by giving the Tendakraut obtained from the Tenda Village above. Inside, a talking rock provides an inspiration speech for Ness while recapping the Sanctuaries he had visited prior, while also revealing the final Sanctuary, the Fire Spring, found in the far west of the Lost Underworld. With this knowledge, the team set out to find the Fire Spring and collect the final Melody.

On the way, the team is able to find a cave leading to a mysterious cave with views of a mysterious spire as well as a destroyed machine.

The Lost Underworld-esque sprites in Mother 3.
  • In Mother 3, when leaving Snowcap Mountain, Lucas and his party use small sprites that are similar to the ones used in the Lost Underworld.
  • There are unused small sprites for the Photo-Man and an Escargo Express deliveryman, which suggest that they may have been plans to have them appear in the Lost Underworld.
