History of Vex Mind

Overview

A Vex Mind (also Axis Mind) is a powerful Vex unit that controls masses of other Vex, usually manifesting as a Minotaur or Hydra, sometimes as other Vex forms (Destinypedia). They appear across many expansions and seasons.

In The Edge of Fate

You deposit motes dropped by Vex into a conduit to draw a Mind out. See Barricade Mind, and The Gorge Strangelet.
