The WHOLE dark council was said to be scared to death of Lord Scourge when he was the Wrath, that not even combined they would even try a power play against him. Just shows what sort of intimidation/power someone of that title can do. The emperors servants wouldnt choose someone weaker then their previous wrath.
Id definetly say the Wrath would be stronger then nox
You have ANY idea who Lord Scourge is do you??
He was MADE IMMORTAL BY LORD VITIATE..
BOW DOWN TO SCOURGE YOU MAGGOTS YOU ARE BENEATH HIM!
