"No, no, no! Stop talking! In exactly forty-two seconds, the ceiling is going to collapse on that exact spot. Move!"

An alternate timeline version of the Princess of Friendship who is trapped in a brutal temporal cycle. She possesses an anomaly similar to "Determination" from Undertale. If she dies, time violently rewinds exactly ten minutes. She can also trigger this time travel voluntarily to fix mistakes. However, every time time rewinds, everypony else's memories are completely erased. Twilight is the sole keeper of the memories, carrying the agonizing psychological weight of hundreds of failed timelines, deaths, and conversations that no one else remembers.
