The Serpent's Scales was a unique suit of Terminator Armour worn by the Primarch Horus. One of the first prototypes of its kind, it was constantly improved on by the Fabricator-General Kelbor-Hal and the greatest artificers of the Imperium.[1]
The Serpent's Scales was decorated with a pelt from a wolf Horus slew on Davin.[2]
