Kek encompasses two subspecies, the Shiree'Kek and the Kek'Shiree, the former having given rise to the latter. They are a social "insectile" Kind descended from of the Dinoponera or giant Amazonian ants. In the aftermath of Brum in the Third Epoch, the Shiree'Kek rapidly developed and eventually conquered all of South America in their warlike early generations during Metabola. As their species matured and thoughts turned inward, the Shiree'Kek evolved into a fiercely peace-devoted people prizing logic and analysis above all else.
Near the close of Gaia's Fourth Epoch, an entire generation of Kek'Shiree is born.
