Tau Empire Symbol

The icon of the T'au Empire.

A Puretide Engram Neurochip consists of a T'au bio-chip that has been surgically implanted into the brain of a Fire Caste Tau Commander, and allows the bearer to access much of the wisdom of Commander Puretide himself. He or she is able to draw upon a great reservoir of tactical acumen when needed through the data contained on the chip.

Puretide Engram Neurochips were developed from prototype versions knows as Swords of Puretide, and are a result of a project that originated with the Tau's unwillingness to lose Commander Puretide's tactical and strategic brilliance when he succumbed to old age, as he was undoubtedly the most gifted Tau Commander of all time.

Upon his death, Puretide's mind was scanned and his accumulated memories committed to a massive holographic program on his birth world of Dal'yth. Slivers of his genius were then copied and crafted into bio-chips that would one day become Puretide Engram Neurochips. The Puretide Engram Neurochip is considered a T'au Battlesuit signature Support System available only to Battlesuit pilots of the rank of Shas'vre or higher.
