The Temple Sanctuary is a room in the Great Temple. This is the room where Samus faces several Splinters and an Alpha Splinter before they eventually turned into Dark Splinters and a Dark Alpha Splinter. She gains the Energy Transfer Module following their defeat. This is the third room in the Great Temple. This room had many gates guarding the paths to Agon, Torvus and Sanctuary Sectors. The Dark Aetherian version of this room is the Sanctum. This room also contains the sleeping Luminoth in cryo-stasis; they are the last members of their species.

- Stasis chambers
- "Object scan complete.
Units identified as hibernetic stasis chambers.
Lifesigns of hibernating bioforms within the chambers are steady. Chambers are made of a number of exotic metals: it would be quite difficult to breach them with conventional weapons."

Compromised hibernation structure.
This cocoon has been heavily damaged. Only remnants of the cocoon shell remain."

- The Emerald Translator Gate that Samus enters the room from (on the path to the Sanctuary Fortress) is absent on her first arrival but is locked when she enters the Splinter battle.
