Wren recognized what he was trying to sing but did not know the words herself. She decided it was better to keep her mouth shut on the matter on magic. In the forbidden kingdom Spellcaster were called upon to bless newly opened mines, harvests every year, the forging of weapons for the "magic guard", and participated in annual festivals every year. The magic guard were a group her kind that volunteer and were trained to protect the lives of the spellcasters. The weapons that were made for them were said to be sharp and strong enough to cut straight through any normal sword. Of course, this is little more than a roomer no one has actually intently tested it. After he put the oil on the machine Wren felt a sharp pinch on her wing and without thought, she wrapped her right wing around to her front to seed what the culprit was. Turns out it was just a simple pincher Beatle and she riped it off of her and threw it straight into the furnace. Her sudden movements also knocked the blanket, that she had around her, off. This left her wing exposed for Robert to see, her wings were mostly black with the leading edge being white with gold highlights mixed in. When she realized what she had just done she froze still with a mortified look on her face. She really didn't know what to do, her wings were mostly black and she could be very easily be mistaken as a demon of some sort. Normally just taking to the sky would solve the problem but she was in no condition to fly or even go anywhere on foot.
