Those he helps to evolve will be lacking in the perks of their ranks but they will have the power. The demon nobles he creates won't have the ability to create a house and the Oath of allegiance. The demon lords he creates won't have the Oath of lordship either and they won't be able to help others evolve. It is because they are already his subordinates and under his house.
The demon lord was right about a lot of things. Her ambush was excellently planned and executed. She was right about not trying to kill him because all the forces she would have sent will have died. She was also right about the window of opportunity she had to subjugate him. Her attempt at making him sign the contract before he evolves was accurate. But she doesn't know the full extent of the trouble he has become for her now.
