The Covenant of Elemia エレミア誓約書, eremia seiyakusho?, lit. "Covenant of Elemia"), also called the Contract of Elemia, is a document written by the Humans and Teru that cooperated to seal Mir, which registers all the limits that were imposed on the use of the resources of the Tower of Ar tonelico. It was decided that all the usage of this extremely powerful facility was to be banned, so disasters such as the one that caused the end of the First Era: the Grathnode Inferia, and the one that caused the end of the Second Era: Mir's Rebellion, would never be repeated again.
