The Temple Vault is an ancient structure hidden deep beneath the sea level in the planet Morag. Every 300 years the vault is made accessible. It is here that the Orb was located.
History
When Star-Lord entered the Temple Vault, he obtained the Orb, but was immediately surrounded by Korath the Pursuer and two others. After identifying himself, Star-Lord ducked as Korath fired upon him, destroying a temple wall. Star-Lord activated his helmet and quickly exited the Temple Vault with Korath and his men in pursuit.
Inside the vault is a mural depicting the four creators of the Infinity Stones: Eternity, Infinity, Entropy, and Death.[1]
