Oryx, after he took the power from Akka the worm, rips them from our dimension, takes them to the home of the Darkness and "completes" them. That is why the Takens powers are a reflection of what they are missing (the cabal centurions are given offensive powers because they are too defensive.)

Oryx uses the power of the Darkness to rip them from our dimension, granting them "truth" and "enlightenment" as taught to him by the Darkness itself. He then sends them back with new powers and new realizations, bent utterly to his will
