Prefect

The Prefect  is a Kett unit type. Prefects wield a power similar to biotics from the Milky Way Galaxy. They can erect an orange barrier around themselves that is sustained by a floating orb. Destroying the orb will bring down the barrier. The orb can also be used as a weapon, sending a Nova-like projectile at its target. Two notable Prefects are Primus and the Cardinal, the commander of Kett Command on Voeld.
