Prophet of Regret (Earth-5875)

"Every member of the Covenant shall walk the Path. None will be left behind when the Great Journey begins. That is the san'shyuum's age-old promise, and it shall be fulfilled!"

- - Prophet of Regret

The Prophet of Regret, born Lod Mron, was one of the three san'shyuum Hierarchs of the Covenant that led the empire and the Covenant High Council during the First Contact War in the 9th Age of Reclamation, of which he was the youngest. Inmature, ambitious and relatively naive when compared to his fellow Hierarchs, Regret started his career as the Vice Minister of Tranquility, where he worked at the side of many sangheili and adopted many of their traits, such as concerns for honor and tradition, leading him to be labeled as a "san'shyuum who thought like a sangheili", a rare mindset among his species, which made him a formidable enemy for the Prophet of Truth.

Early life
Lod Mron was born on August 22nd, 2332, on High Charity. In 2512, 23rd Age of Doubt, Regret served within the Ministry of Tranquility as the Vice Minister of Tranquility, where he gained the reputation of being confrontational, a trait he gained from the sangheili he closely worked with. In 2513, he rose to work alongside Ord Casto, the Minister of Fortitude, and both conspired to become Hierarchs to achieve more power within the Covenant.

As part of their conspiracy, Tranquility pretended to sympathize with the Roll of Celibates, of which comprised one of the three Hierarchs they wanted to dethrone. He pretended to be the father of two children the Hieararch unlawfully fathered, blackmailing him until he stepped down from his position. They were later helped by the Ascetic Hod Rumnt, who finally abled them to rise to the post of Hierarch through the subterfuge of their previous three leaders.

As a sign of gratitude towards his aid, Casto and Mron offered him the chance to be the third Hierarch at their side, which he relutanctly agreed with, but saw no other choice knowing about their secrets. With his help, the three san'shyuum ascended to become Hierarch, and Mron chose the regnal name of the Prophet of Regret.

Outbreak of the war
In February 2525, the Prophet of Regret approached his fellow Hierarchs to indulge about the "reliquaries" found on the distant world of Shanxi. While he and Mercy analyzed all the data the soldiers were able to retrieve in the planet, Mendicant Bias, the Oracle of the Dreadnought reactivated disclosely to the Prophet of Truth, revealing that the humans were "Reclaimers" who were left behind, which proved a major aspect of the Path and its Great Journey to be false.

After Truth heard this revelation, he kept it a secret from both Mercy and Regret, believing such an information, if public or shared, would certainly lead to the destruction of the Covenant from the inside. They then declared war against humanity, under Truth's pretense that humanity were heretics that deserved to be exterminated duo to their very existence being a threat to the forerunners.
