The Archon assigned to the Heleus Cluster eventually began deviating from kett protocols. The uncoordinated and separated angara were swiftly defeated, though the kett would continue to have to deal with various resistance movements and later the unified Angaran Resistance led by Evfra de Tershaav.

When the angara encountered them, the kett lured them into a false sense of security with gifts and offers of friendship, before kidnapping their leadership and providing information which provoked arguments between angaran worlds. The kett are not native to the Heleus Cluster, which they call Sector 1-19-NYKZ, and began invading it in 2744. They begin developing an exaltation serum for krogan, but the process is incomplete and the partially-exalted prototypes, called Behemoths, are mindlessly hostile to both non-kett and kett.Įxaltation unified the kett homeworld of Sarhesen, and in time the other worlds that the kett empire conquered. Kett lifespan is currently undetermined, though it is known that the Archon of the Heleus contingent has been active in cluster affairs for over seven decades.įollowing the arrival of the Andromeda Initiative, the kett become interested in exalting Milky Way species. They are physically kett, for all intents and purposes, and exaltation appears to be permanent and irreversible thus far. Internal scans show kett organs, not angaran ones. However, nothing from the original species' body is left: a kett exalted from an angara, for example, only has traces of angaran genome remaining. One such trait is that kett can survive for limited periods in inhospitable environments without protective suits, including vacuum.

Kett biology retains traits taken from many other species. Heleus Cluster species that have been subjected to exaltation include the challyrion, who become wraiths, and the angara, who become Chosen and Anointed. To build an army or replenish their numbers, kett simply capture members of other species and transform them through exaltation. Kett mastery over genetic manipulation enabled them to develop a serum to rapidly convert other species into obedient kett, which became the basis for exaltation. The kett began adding beneficial genes from other species into their own genome in order to continually improve themselves, which they refer to as harmonization. It is speculated that exaltation arose long ago in kett history when their genetics reached a point of stagnation, leaving the species unable to breed through natural means. Kett possess no reproductive organs, and they reproduce only through an artificial process called exaltation. Kett have very low-pitched voices, and those who have marginally higher voices are generally considered female. There are no visible distinctions between "male" and "female" kett of the same type.
