You approach the door that leads to the room where the quarrel is taking place. There was Tyrael himself, the Archangel of Justice, and Imperius, the Archangel of Valor

Imperius: Tyrael! The ancient law of heaven strictly forbids us to interfere in the affairs of mortals. You started this deliberately!

Tyrael: And what am I guilty of before Imperius? That I bring justice! And you, like a coward, hide behind your throne!

Imperius: Shut up!!! You will answer for your will!
