Sekrion is a Vex Axis Mind that controls and oversees the Vex's expansion through Venus' planetary crust. It takes the form of a large Hydra that uses its constant barrage of Void blasts to quickly eliminate enemies while simultaneously defending itself with its indestructible shield.
Events of The Dawning Edit
Two years after Sekrion's defeat, the Vex restarted their expansion throughout Venus. They rebuilt and upgraded Sekrion with a new chassis and technology from the Vault of Glass. Meanwhile, the Taken, despite Oryx's defeat a year prior, organized an invasion and attempted to take the Nexus Mind. They were either successful in taking Sekrion, or were beaten to the Nexus Mind by a Fireteam of Guardians. Regardless, it was destroyed once again.
