Sky Temple Grounds
From Wikitroid, the Metroid wiki
The Dark Aether version of the Temple Grounds, the Sky Temple Grounds is the area surrounding the Sky Temple. It is a very dangerous place, with its atmosphere very damaging, even for Samus Aran's Dark Suit. Many Ing guard the area, making sure none get the Temple Keys hidden throughout the land. Something to point out about the Sky Temple Grounds is that it's the only area in the game without a Save Station. Samus faces Dark Samus here, at the end of the game. It hides three Sky Temple Keys.
