|~ Prophet of Mercy|
The High Prophet of Mercy, born Hod Rumnt, was one of the three Prophet Hierarchs who led the Covenant Empire (the others being the Prophet of Truth and the Prophet of Regret) and one of the main antagonists of the Halo trilogy, and a major antagonist in Halo 2. He was the eldest of the three Hierarchs and
Mercy was originally a Philologist and a Councilor. He was present along with the Vice-Minister of Tranquility and Minister of Fortitude when the "Oracle" 032 Mendicant Bias revealed that humanity was in fact the true Reclaimers chosen by the Forerunners, making the religion of the Covenant false. The Philogist thus agreed with the Ministers to keep the secret from getting out, as it being revealed would trigger the collapse of the Covenant and overthrow of the Prophets.
The Philogist later became one of the three Prophet Hierarchs after the Vice-Minister of Tranquility blackmailed the previous three into resigning. After becoming the Prophet of Mercy, Mercy and his fellow two newly appointed Prophets had the Covenant declare war on humanity in order to keep the secret of the Reclaimers covered up.
When the Great Schism occurred, Mercy along with Truth and the Brutes made their way to the Phantoms on High Charity. The Flood suddenly attacked them and one attacked Mercy, Tartarus was ordered by Truth to not save Mercy because he wanted to become the ruler of the entire Covenant Empire. After following the order and abandoning Mercy.
In that moment, Master Chief found him still being attacked by the flood just when Truth and his followers escaped. John asks to Mercy where is Truth going and Mercy tells him that Truth is going to the Planet Earth to finish what they started with the addition of none of humans will be left behind. John then removes the Flood parasite off him and The Prophet of Mercy dies.
