Lucius the Eternal, clad in the nightmarish Armour of Shrieking Souls
The Armour of Shrieking Souls is a unique and exceptional suit of daemonic Power Armour worn by Lucius the Eternal. Imbued with the faces and bodiless souls of all those whose spirits were trapped by Lucius over the millennia, through Lucius' powers of regenerative immortality gifted to him by his patron Chaos God Slaanesh, the armour can discharge the cacophony generated by the tormented essences trapped within the armour as a psychic assault at the will of Lucius. In this respect the armour acts much like a Doom Siren, a powerful sonic weapon used by Slaaneshi Noise Marines. Being an incredibly potent artefact of Chaos it also confers an amount of invulnerability to its wearer.
