The High Prophet of Restraint was a High Prophet during the 23rd Age of Doubt. He, along with the High Prophet of Tolerance and the High Prophetess of Obligation, led the Covenant High Council until 2524.
As of 2524, the aging Prophet's tenure had been marked with scandal involving his various sexual exploits, most notably the impregnation of a young female San'Shyuum. While such a thing was not prohibited, Restraint was on the Roll of Celibates, those San'Shyuum who possessed recessive genes and were forbidden from siring children. Having lied about his status to his lover, the new mother demanded she be allowed to have her children, which the Prophet eventually agreed to. Learning of this, the Minister of Fortitude had the Vice Minister of Tranquility give the invocation for the upcoming Birthing Period, where he advocated ending the Roll of Celibates. Believing him sympathetic, Restraint approached the Vice Minister and offered him the full Ministerial post if he claimed the children as his own.
The Minister responded by offering to keep the scandal quiet, only if Restraint stepped down as one of the leaders of the High Council. The Vice Minister then succeeded him and became the High Prophet of Regret.
- Like most of the other High Prophets, his name has some irony to it; he stepped down as a result of high sexual exploits, therefore showing his lack of restraint.
- His "mate," along with the High Prophetess of Obligation, the High Prophet of Truth's "Concubines" and Chur'R-Yar, are the first female Covenant mentioned in the entire Halo series.
