Voidmaker

The Voidmaker generates a field that annihilates both matter and energy within its effective radius. It is described as among the weaker weapons in the Demiurge's arsenal, with Astrophage considered more powerful. Its destructive capability extends to matter at the subatomic level — it successfully destroys matter whose quarks had endured since the earliest moments of the universe.

The Voidmaker is tested against asteroids in the Annica system during Hadrian Marlowe's years of exile there, confirming its ability to annihilate matter at the quark level. During events on Danu, Hadrian orbits the Voidmaker over the planet as part of a plan to trap the Watchers and fire it with himself and the Watchers inside the radius, but the plan fails because he cannot obtain a clean shot.
