The Tohaa are an advanced alien race and a long time enemy of the Combined Army. They are the guardians of a treasure of knowledge known as the Digesters. The Tohaa have fought of the Evolved Intelligence countless times and they now need allies. Humanity in a perfect candidate in the eyes of the Tohaa. The big question is; will the Tohaa really ally themselves with humanity, or will they just use humanity as a buffer against the onslaught of the Combined Army, which the Tohaa withstood for some time now.
The Tohaa use advanced bio-engineering and are known for their viral weaponry and their symbiont relationship with their armours. Next to that, they have the ability to evolve other races so that they become more resilient and more intelligent, but probably not too intelligent.
Tohaa society is build around the number three. Everything comes in three and so does their fighting forces. The Tohaa Trident is a fierce enemy of the Combined Army and of humanity, if they wish to declare them an enemy.
