The Eye Unseen

This ancient augmetic was first bequeathed to Interrogator-Chaplain Enoch by the Watchers in the Dark, and has since been extracted and re-implanted in a string of Dark Angels heroes. It is said that no secret can escape the gaze of the Eye, nor guilt, lies or any obfuscation. Those fixed by the glowing lens of the Eye of the Unseen have their deepest wants and fears laid bare, and their every weakness exposed. The sensation is said to be akin to Catachan harpoon-bugs crawling across the inside of the skull, and it is all the victim can do not to drop to their knees and confess all.
