Opposition

The Opposition was a Sangheili Covenant remnant faction that rose from the ashes of the Covenant's downfall in 2553 and was founded and led by Zexi 'Nrahom, alongside Shaxa 'Zosam, and mostly consisted of female Sangheili members with little to know males. Like other Covenant remnant factions, Zexi and Shaxa considered the Opposition as the legitimate successor to the previous Covenant which is known by its members as the Revived Covenant, despite its far-off Covenant name with other names being the Feminist Covenant by members of other factions and the UNSC. The faction waged a war against the Covenant Loyalists from 2553 to 2554 and later other remnant factions from 2554 to 2558 before being absorbed into the Swords of Sanghelios.

War against the Loyalists
After losing their loved ones in the Great Schism, both Zexi and Shaxa had escaped the massacare of every Sangheili in the Covenant and found refuge with other female Sangheili, luckily who were trained to use weaponry, and convinced them to band together and fight against the Covenant Loyalists in order to avenge their lost loved ones. This faction became the first widely known female Covenant faction by the UNSC, Covenant Loyalists and the Separatists.

First fighting on the world of Malurok, the Opposition had hoped to crush a peace treaty meeting between the Covenant Loyalists and a splinter group of Covenant Separatists to work as double agents whereas they were successful in breaking the meeting but resulted in a pyrrhic victory for the Opposition.
