Danielle was a Rank 3 Angel of Supremacy who has gone through the most rigorous spy training of the Heavenly race. She was stationed in a mountain range less than ten kilometers of the force field created by the Ten Tower Formation.
She had trained a Path Technique known as Seamless Integration. This technique was arduous to practice, but she reached the level where she could blend with her environment.
This allowed her to hide from even the consciousness of Rank 4 life forms, as long as they do not focus on her exact location. The most minimal movement could break her cover, so she had to maintain complete inactivity.
Her task was to monitor the Magi invader force's movements and contact the headquarters of the Heavenly race whenever someone entered their domains, no matter their power.
The dukes knew it was just a group of Rank 2 life from the ones who opened a portal to the Abyss, so they could not let anyone enter their territories again unnoticed.
