A mother gives birth to a baby girl, and then the baby is taken away to be experimented on using Hex crystals, putting the Hex crystal in a machine then using a beam to try fusing both. After trying to fuse the baby girl with crystal shards, the shards shined brightly and then shattered. Jayce and Viktor thought she was a failure and cast her away in Zaun AKA The Undercity but little did they know, she was indeed one with the Hex crystals and now has magic powers like no one has ever seen or thought possible. She could focus her energy on any part of her body, make physical weapons with her mind, and enhance her speed and strength, but the baby girl didn't know. A random woman was walking around cautiously watching her surroundings since in the undercity, anything could happen, especially with a woman who is alone. She found the baby girl in an alleyway. Feeling bad for her, she picked her up and decided to name her Rose, then took care of her for 10 years before being killed by Piltover guards for absolutely no reason.
