Roots of the Blackthorn

Emily stared at the marking on her chest in the mirror, which she hadn't noticed when she got dressed earlier that morning. It bore a striking resemblance to the root-like markings that once marked the backs of her brother's hands. But what did that have to do with her?

"Ah!" She winced in agony as a searing pain shot through her, akin to a lightning bolt striking her chest, serving as a stark reminder of the fragile state of her soul. The pain refused to relent, coursing through her body and causing her to lose her balance and collapse to the ground. 

Upon hearing a faint noise coming from inside the room, Julia turned the doorknob and entered, letting out a gasp. 

"Princess! Are you alright?!" Julia asked, her voice filled with alarm. She quickly bent down to help Emily raise her head, who was hunched over in pain, her face hanging low towards the floor.
