Agioktis

Agioktis, Martyr Mind is a Vex Mind that the Vex built to drain the Light of Saint-14. It is the boss of the Corridors of Time Part 2 mission in the Season of Dawn story.

Encounter

The fight begins at Infinity's Siphon, after Saint-14 is trapped in a Vex prison and the Martyr Mind arrives. It attacks with a line rifle and Void bolts, summons volatile Seeker drones, and can detain attackers in a bubble.

When it loses about a quarter of its health, it retreats behind a Vex shield and summons a Shackled Minotaur. Killing the Minotaur Ultras yields Arc Charge, which must be deposited into a Vex Conflux that holds up the barrier. After the third charge, the Mind teleports the Guardian into a detainment field, and Saint-14 destroys it moments later.

A later form, Agioktis, Archived Mind, returns in a Minotaur body in the Episode: Echoes mission Mission: Shell.
