The properties of terrazine appear to be foreign to the material universe—it has been speculated that terrazine's origins lie within the Void, as on Slayn, it was found in the presence (or emitted) large amounts of Void energy. The presence of terrazine in large amounts can sustain Void shades, albeit not at full strength. The Tal'darim used terrazine to become closer to Amon and to "peer beyond the veil." Terrazine has a coppery, blood-like smell. Terrazine can be used as a power source for power suit (or similar) technology.
