The Watcher's Axe is a powerful artefact combining a Power Axe and a master-crafted Bolt Weapon known as the Eagle's Scream. Watcher's Axe crackled with golden lightning and it's said that it can bisect the sarcophagus of a Chaos Helbrute with a single swing. It is wielded by the Adeptus Custodes' Captain-General Trajann Valoris.
