Constraint field

Constraint fields were a form of Forerunner energy field used to restrain individuals. The interior of a a constraint field was pressurized against vacuum, and a constraint field could be merged with another field. Warrior-Servants were capable of generating constraint fields at will; for example, Glory of a Far Dawn used two constraint fields to secure Bornstellar Makes Eternal Lasting and Splendid Dust of Ancient Suns as they escaped the Forerunner capital during Mendicant Bias' attack.
