The Aether House (Japanese: エーテルハウスAether House) is a location on Ula'ula Island in Alola, located on Route 15. It is the Aether Foundation's largest base on Alola's main islands, with one of its purposes being an orphanage for human children and Pokémon. Its headmaster is an Oranguru. Acerola is among the children who live here.
Much like every other facility owned or run by the Aether Foundation, the Aether House features a predominantly white color scheme. The main foyer contains a reception desk which stands in front of a staff room the player cannot access, and four doors leading to other rooms, two of which can be accessed by the player. An Oranguru, nicknamed Headmaster (Japanese: エンチョーPrincipal), can be seen at the back of this room. The door to the left leads to a playroom with some shelves, toys and a TV; while the door to the right leads to a bedroom with a table, some bookshelves, two bunk beds, a Mimikyu, a Wimpod, and two Aether Foundation Employees. During the post-game, the Aether scientist in this room will give the player a Porygon.
