Lucifer Cave:
Lucifer and his angels landed outside the cave.
"You can make yourself feel at home, because here will be your new home until the war." Lucifer told them and he was about to enter the cave, still carrying Rae, when they heard the sound of snapping of wings in the air. This shows someone is landing.
Stopping in his stride as all his angels took their stance, ready to fight whoever it is.
Lucifer hoped it was Tharollin who have come back with the remaining bone.
The person finally landed in their midst.
But instead of Tharollin he was expecting to see, he saw a man. By his looks and white wings with lovely clothes he had worn before in heaven, it was an Angel.
His Angels wanted to attack the man but he gave them his signal not too yet. The man wasn't fighting them yet.
"What are you doing here holy one?" He asked the Angel instead.
