Galactic ruins

Mysterious galactic ruins of an unknown civilization are present in the Extreme Galaxy in Metroid EX. On the outside, the ruins appear in a diamond-shape, split into four sections with a core, and two Saturn-like rings around them.

Greed sought out these ruins after locating a tablet inscribed with the location of the ruins. It also revealed the presence of an ancient treasure of godly might, which he hoped to acquire and use to wreak havoc on the cosmos. The treasure is located behind a large door, which can only be opened using a sacrifice. Greed intends to use Samus Aran, who is captured and last seen attached to apparatus meant to open the door. Joey Apronika and Diesel break into the ruins to save Samus and disguise themselves as hieroglyphs using dust. However, they are captured along with Greed's general Knight and sentenced to execution.

Who once resided on this planet is never explained. Though they are not of Chozo origin, hieroglyphic text on the walls resembles their language.

Tablet message
"To the one who binds the past and future: the ancient treasure is liken to the power of the gods! Take heed, ye who look upon it! It holds the power to rule the universe! Take heed, ye who touch it!"
