The Raven Alliance and the Societas Corvus Corax

The Raven Alliance, the Societas Corvus Corax, ensures that humans cannot transcend time and their worlds. But the perfect formula for this has not yet been found, and so Sophia, who actually lives in the 19th century, meets Tom, who is studying in the 1990s.

The two worlds collide again and again, leading to unforeseen consequences that are now unstoppable. While the members of the Raven Alliance, who can change their form, work diligently to prevent the worlds from changing with the help of mathematics, Sophia and Tom face the challenges of their time.

What are the consequences of their encounter?
