Auramite is a material of unknown provenance but extraordinary resilience used to construct the customised, golden suits of Power Armour worn by the Adeptus Custodes, the bodyguard of the Emperor of Mankind. It is said to be similar in composition to the heat-and-shock-resistant ceramic synthetic known as Ceramite used in the crafting of Space Marine and all other forms of Imperial Power Armour.
