The Evidence Vault was a chamber located in the Oan Citadel on the planet Oa which was the homeworld of the Guardians of the Universe. It served as a site where their Green Lantern Corps could store confiscated weapons and items for storage. Among the various beings defeated by the Green Lanterns was Agarushnawokliag, the Dismantler of Worlds whose energy weapon was kept within the vault.
