Prophet of Regret

The High Prophet of Regret was the youngest of the three High Prophets that lead the Covenant High Council during the Human-Covenant War. He is also one of the main antagonists in Halo 2 as well as in Halo Wars. Rash, ambitious, immature and naive compared to the other Prophets, Regret originally served as Vice Minister of Tranquility, where he worked frequently with Sangheili and had adopted some of their personal traits, such as a preoccupation with honor and personal arms. However, he also exhibited traits of alcoholism and smoking. Still, Regret was intelligent and fiercely opposed to Humanity through the course of the Great War and expected his soldiers to obey him without question.

Age of Doubt

During the 23rd Age of Doubt, 2527 by the UNSC Military Calendar, Regret held the post of Vice Minister of Tranquility. He was unique among the Prophets for his confrontational demeanor, a trait he gained from working with Elites. He informed the Minister of Fortitude about the existence of Harvest and what they believed to be a vast repository of Forerunner artifacts. (These "artifacts" were the Reclaimers on the planet.) After conspiring with the Fortitude to gain these artifacts for their own use, he helped him by pretending to sympathize with those blacklisted from reproducing due to inbreeding, which included the Prophet of Restraint. After pretending to be the father of a child Restraint had unlawfully fathered, Tranquility blackmailed Restraint into stepping down from his position as High Prophet.

Before their coup, the Prophets visited the Oracle, which was actually the long dormant Mendicant Bias, an ancient AI stored in the Forerunner Dreadnought that had not spoken to anyone for hundreds of years. When the Luminaries of Harvest were entered into its matrix, it revealed the symbols had been misinterpreted -- that humans were equals to the Forerunner and the Covenant had been mistaken in their beliefs. As it tried to launch the Dreadnought from High Charity the Lekgolo worms inside the Dreadnought short-circuited it and stopped Mendicant Bias. Fortitude, Tranquility and the Philologist made the decision to disconnect the Oracle from the ship and decided to eradicate humanity before any of the Covenant learned that the most basic premise of their faith was false, and that "living gods" would probably replace the Prophets. As such, their ascension was made, taking the names of Truth, Regret and Mercy.

Age of Reclamation
Human-Covenant War

Obsessed with the Forerunners and the prospect of activating the Halo Array, Regret dispatched Arbiter Ripa 'Moramee on numerous missions throughout Covenant and Human space to find the means to do this, choosing him for his ruthlessness and undying loyalty. Eventually, after or during the Third Battle of Harvest, Regret discovered a Forerunner relic buried in the planet's northern polar region. Dispatching a force led by 'Moramee, valuable information was recovered. With UNSC forces closing in however, Regret ordered that the relic be destroyed to prevent the retrieved information from falling into human hands. Against his instincts, the Arbiter obeyed. Later at the Apex he discussed with the Arbiter his plans to activate the Forerunner ships located there, when he could not activate the artifact himself, he ordered the Arbiter to capture the human female encountered at the Ice Relic and bring her to the Apex. Later when the Arbiter returned with her, he was in disbelief, saying "you would hardly think them a threat". When they learned the Humans were closing in on them Regret evacuated to High Charity. However, Regret's plans to use the dormant ships were foiled when the crew of the UNSC Spirit of Fire overloaded the Shield World's internal sun, destroying all the ships, as well as cause the death of 'Moramee.

Battle of Charybdis IX

Three years later, Regret was present at the Battle of Charybdis IX, with his personal Assault Carrier, Infinite Sacrifice, where he oversaw Thel 'Vadamee, and the glassing of the planet. He then called upon Thel to find the source of Human-modified Covenant Weapons, and bring them to the Prophets. Little did Regret know, that he was in fact, interfering with the Prophet of Truth's plans to find the location of all the Human colonies and also Earth. However, their plans eventually fell back into tandem.

First Battle of Earth

In 2552, Regret served during the destruction of Halo Installation 04 and helped condemn the Sangheili Supreme Commander (later the new Arbiter) who was responsible for the loss of the ring. The Prophet of Regret subsequently led the first attack on Earth with a small fleet of two Assault Carriers and thirteen Battle cruisers. He may have been directed to Earth by a Forerunner artifact on Coral to search for Ark, but he apparently had no knowledge of a human presence on Earth or that it was his enemy's home world. He sent Ranger Elites and Boarding Craft to destroy the Orbital Defense Platforms Malta, Athens, and Cairo, so he could push through into the heart of Africa. Despite the Master Chief's actions, his ship made it to the ground and deployed the first full-scale invasion force of Covenant on Earth.

After landing in New Mombasa, Regret's forces searched the city supported by Scarabs and many Phantom dropships. As the Master Chief approached his Carrier, Regret's ship initiated a Slipspace in the middle of New Mombasa to escape and regroup. The forces generated by the jump heavily damaged the city. The move was so surprising that only the In Amber Clad and four other UNSC ships were able to follow the Carrier.

Battle of Installation 05

Regret's Carrier deployed ground and infantry forces onto the surface of Installation 05, and set up a presence around a temple in the middle of a lake, from which Regret began his religious sermons. He transmitted an apology to the Prophet of Truth, indicating that he couldn't have known that the humans would be there or in such force. Truth responded that only Mercy had spared him from public condemnation. Nevertheless, High Charity and the Second Fleet of Homogeneous Clarity rushed to the new Halo, and a flight of Phantoms was deployed to rescue the Hierarch.

In Amber Clad arrived in system soon after and deployed ODST forces on Installation 05 along with the Master Chief to locate and kill Regret. The operation was a success, with the Spartan breaking through Covenant defenses, killing Regret and his bodyguards. Soon afterward High Charity made a jump to the ring and ordered one of the nearby ships to use its Gravity Lift to destroy the temple, nearly killing the Spartan and leaving Regret for dead.

Regret's body was later assimilated and reanimated by the newly formed Gravemind. He expressed annoyance with another captive of the Gravemind's, 2401 Penitent Tangent, and reacted to the presence of the Arbiter, warning him to forget any heretical suggestions made by the Monitors and the humans and to pursue the Great Journey. What remained of Regret was destroyed with the Gravemind when the replacement for Installation 04 was prematurely fired by the Master Chief and Cortana during the events of Halo 3.
