Lights of Sanghelios

Honor Guard Ultra, also known as the Light of Sanghelios or "Helios" for short, is a Sangheili Honor Guard rank in the Covenant. They are among of the most distinctive Sangheili combat units. The name "Lights of Sanghelios" comes from a star cluster near their home planet. They commands the 'lower' Sangheili Honor Guardsmen that protect the High Prophets.

Description
Honor Guard Ultras sport the same ornate armor as the rest of the Honor Guard, with the exception being that the base armor they wear is white instead of crimson red. This color is consistent with the Sangheili Ultras of the regular Covenant army, hence their title.

The Honor Guard Ultras are likely more skilled than their subordinates, with many years of experience in the Covenant Honor Guard services, which is particularly impressive considering the prodigious combat abilities of any in the Honor Guard. Because of their skill in close combat and rank over the rest of the Sangheili, they were likely killed first at the start of the Great Schism, similar to what happened to the Councilors.

The San 'Shyuum use them as personal guards for their living quarters. The Minister of Fortitude, later known as the High Prophet of Truth, used these special guard units for his own personal protection during the Twenty-third Age of Doubt.
