Vox Espiritum

The Vox Espiritum is a Space Marine relic.^[1]

Developed by Belisarius Cawl, the Vox Espiritum is a powerful neural amplifier that causes its wearer's voxed utterances to resonate on a modulated and heavily warded frequency. Though highly experimental and perhaps dangerous, it allows its user to project their bellowed commands directly into the minds of friend and foe alike.^[1]
