Empyrean Brain Mines are a form of non-lethal weapons technology used to stun targets employed by the Grey Knights Chapter of elite Space Marines and the agents of the Inquisition. Empyrean Brain Mines are based on captured Ghost World technology.
When triggered, they latch onto the victim and send a pulse of energy directly into their brain, momentarily stilling their motor functions and leaving them unable to act.
The effect is only temporary, as the brain mines are prone to burning out after a few solar seconds' use, but leave an enemy incredibly vulnerable in the interim.
