Emma is a Gryffindor, in her 5th year. Just your average Hogwarts student. She's definitely not failing, but she isn't top of the class either (though she exels at Arithmancy). She isn't popular, but she also isn't the one everyone picks on. She's a half-blood, has a few close friends, and a loving family, including a muggle mother, a wizard father, a brother who is in his seventh year, and a sister who is in her third year. In her opinion, her life is pretty much perfect. Until, that is, a portal opens, she lands in an entirely different world, and everything gets turned upside down.
Riley is 15 and an Avenger. She has been for as long as she can remember. Well, ok maybe not an Avenger, but she's lived with Tony and Pepper almost her entire life. You could always find her helping him building something, while Pepper would try and get them to do something 'productive.' Riley has always wanted to help save people, and so when Tony thought he found the Super Soldier Serum, he gave it to her, knowing it was what she wanted most. Turns out though, it wasn't the serum, but it did give her the power to shoot fireballs! She didn't MEAN to make Doctor Strange open the portal, but he got kinda mad when made a joke that he couldn't actually go to other universes. Well, turns out he can (but it really was just a joke!), and she's in a different one now.
Two girls; different universes. Will they become friends, ally's, or enemies? Or, more importantly, will they ever get back home? Or will they be stuck in this world forever?
