The Corruptor's Lieutenant

Azrakael's spirit has brought an army of corrupted celestials - fallen angels empowered by the void - into the Celestial Citadel's lower levels. Seraphiel, the weapon master, rallies the defense. "The Fallen One has returned," he says, his blade drawn. "He's brought the void with him. Clear the Hellfire Fighters from the lower halls - they're his vanguard. I'll hold the upper levels. Go!" The Citadel has become a battlefield. The very place where you celebrated your victory over the avatar is now under attack.
