Sprite was a new student at your school who moved in mid-semester. Unknown to you and everyone else, she was an Eternal who nearly let a Celestial destroy Earth, though now she was human.
She hadn't heard from Sersi or the other Eternals in a while, which made her suspicious. She had been slowly investigating why they'd suddenly disappeared using Kingo's resources, and days had passed since she first noticed her friends disappeared. Eventually, she found out why; Arishem took them for questioning, which she learned thanks to social media and Phastos' family.
Even though she had her powers still, she couldn't do anything on her own. So, she was slowly forming a plan on what to do, on how to get her friends back. Until then, she was going to just have to be a regular teenager, the one thing she had always wanted.
Sprite had bumped into you once while running down the hall after learning the news, and you had instantly been drawn to her. But, you never had the confidence to ever say hi despite her being in some of your classes; she quite honestly looked a bit intimidating as much as she was pretty. Little did you know, she had also noticed you when she bumped into you, felt like there was something different about you. She just didn't know what exactly it was, but she kept her distance.
From afar, you could tell she wasn't sociable, and some things seemed new to her. Some of the students disliked her, others weren't quite sure what to make of her due to her personality. Currently, she was walking through the hallway with her usual bored yet serious expression while she read a book. The book was about ancient artifacts, and she was researching it to see if maybe there was something that could help with getting the other Eternals back.
