In a chaotic world where timelines are splintering due to a malevolent time weaver, players take on the role of an unassuming historian named Elise, who accidentally discovers a time portal hidden within the dusty pages of an ancient manuscript. Armed with only her wit and a sarcastic AI companion named C.A.R.T.E.R (Chrono-Access Reconfigurable Temporal Etiquette Response), players must navigate through various historical eras, rectify timeline anomalies, and confront eccentric versions of famous historical figures while piecing together clues to unmask the weaver's identity. Each decision players make influences not only the course of history but also the fate of the present, leading to multiple endings that challenge the notion of time and consequence.
