Initial experiments on how to harness the children's powers though led to several fatal accidents, which showed the danger their uncontrolled powers could wreak both on themselves and on others. It was the work of an Orokin researcher named Margulis that led to a breakthrough; through dreams, the children could focus and control their powers. However, this research would then be taken from her after she was executed for trying to protect the children, and used to create a process known as Transference; the children's consciousness's and powers could be remotely channeled through a surrogate body called a Warframe: a specially-made techno-organic humanoid battle frame designed to enhance and focus the children's powers, using a device known as a Somatic Link. Not only did the process grant greater control over their powers, but with no fear of self-destruction the powers could be used to their fullest potential. The survivors would be placed in Somatic Link pods in a facility known as the Reservoir located on the Moon, to control their surrogate bodies in a secure location away from their enemies.

These operators, newly christened as the «Tenno», were taught the ways of war. With the combination of advanced technologies and esoteric powers, the Tenno began to turn the tide against the Sentients, allowing them to vanquish the Orokin's enemies across many battles.
