The Iron Grimoire reports that Janus, one of the first Grey Knights, found this xenos device that was said to project a light-years-spanning field that daemons could not enter. It was lost until agents of Inquisitor Valeria located an item that matched its description on Cavlock. If true, it was destroyed when Inquisitor Darkhammer declared Exterminatus on that world before the Valeria could recover the Forge.
