Rhyn's powers were beyond even Gabriel to control, and the unfortunate immortal was a loose cannon that'd accidently almost destroyed the world more times than he could count.
He couldn.t bring himself to include Rhyn in the picture and hoped Katie came to her senses one day and dumped the half-demon before the worst happened, and she ended up extending the bloodline of the loose cannon that was her mate.
The demon before him looked down but didn't object, understanding his place. Unlike Immortals, demons obeyed their leaders. But maybe, next time, lack of discipline in his enemies would work for Darkyn. He'd failed to takeover Death's domain or to kill her. It would take Gabriel a very long time to learn how to rule over the dead, and Rhyn was a loose cannon as a leader for the Immortals.
