The Confirmer served alongside the Didact during the Human-Forerunner War, and provided his brevet mutation. Following the surrender of the San'Shyuum he was placed in charge of maintaining the quarantine around their homeworld. He spent the next 10,000 years serving aboard the Deep Reverence as it watched over the planet. As time went on, his ship became regarded as a memorial, and as his colleagues died over the centuries their Durances were shipped to the Reverence.
