Lauren Marie Wolfram "Ren" (Fal)cey (Bav)aridge, was supposed to have been summoned into a medieval fantasy universe where kingdoms fight over the freedom of heroes... except she wasn't. Her roommate, Reggie got it instead. Instead of that, she's just a normal young woman who plays MMOs by day and works as a bouncer by night. Or was.
Ren wakes as a smart diamond dog with a new name and a rootbeer flagon pin on her vest after creating a new character in Equestria Online... which really turns out to be a one-way ticket to a new world. She still keeps her prosthetic arm and eye, so there's that.
