Mikhail and Nikolai

Mikhail and Nikolai were feared long before anyone knew their names.Born in Russia over 567 years ago, they were hybrids created through forbidden experiments. Whatever was mixed into their blood erased most of their humanity. They stopped aging, stopped feeling guilt, and eventually stopped caring about people.To hide from those hunting them, they enrolled in a high school under fake identities. Their cold stares, emotionless expressions, and violent reputation quickly made them outcasts. Students whispered that they weren't human.
The rumors were true.When a group of classmates broke into an abandoned part of the school to expose them, they discovered a hidden Backrooms entrance beneath the building. There, they learned the truth: Mikhail and Nikolai had spent centuries feeding the Backrooms with anyone who threatened their secret.The twist?The hybrids weren't trapped in the Backrooms.The Backrooms belonged to them.And every student who vanished over the years had never actually left the school. They were still somewhere in the endless halls, hunted by two immortal predators pretending to be teenagers.
