Commander Re'gish Wamik was a Elite Field Master in the Covenant military. He served during the Harvest Campaign in the year 2531.
During the final stages of the Harvest Campaign, Wamik commanded the Covenant forces that found the doorway to the newly-discovered Forerunner relic. He sent a message to the Prophet of Regret informing him of their findings and requesting that he send the Arbiter so that they may open the Relic.
It is unknown if Re'gish died or survived on Harvest, but it is probable that he fought with the Covenant forces attempting to prevent the UNSC forces from disabling the Covenant bomb in the Forerunner relic.
