Whether it was a demon, ghost or some sort of spirit that had possessed Xanthippeia's body she was grateful because all she could see was red. Having to walk in on some magical, dark and daunting creature trying to harm her baby sister sent Xanthippeia on a tailspin. She could barely even feel her limbs when she jumped up and attacked the thing.
It wasn't a shadow per se because it took the shape of a man mostly but there was nothing human or even natural about it. For one it didn't have any eyes but sunken black pits where its eye sockets should be so it was a wonder it could even see. Secondly, it had more arms than the standard two and it seemed to not have legs as it hovered just slightly off the ground. If she didn't know any better she would have thought this creature was a creepier version of the grim reaper.
