Borer (EXverse)

A borer is a type of slipspace drive created and used by the Covenant and its remnants. It is a spacecraft propulsion system capable of making transitions to and from slipstream space and by extension allowing faster-than-light interstellar travel.
== History ==
== Overview ==
Being more technologically advanced than humanity, the Covenant have numerous advantages in slipspace propulsion systems. Whilst the human Shaw-Fujikawa engine is said to “punch” a hole between realms using brute force, Covenant engines instead take a small rupture and delicately enlarge it with surgical precision. This allows the latter to execute far more accurate slips.
Covenant drives are generally more flexible and powerful than those of humans. They have thrice been seen to execute in-atmosphere slipspace transitions (although the first time the drive in question was controlled by a human AI). In addition, Covenant drives can execute successful slips even if underpowered.
