🧠 The Narrative

Lumina signs a major contract with the Ministry of Education to modernize school infrastructure, but Highschool 53 hides a darker secret: a covert Erebus facility studying post-genetic-modification human behavior.

After a suspicious “incident” legally closes the school, Ahmed (a maintenance technician) is sent on a routine night shift. The moment he enters the basement, a self-lockdown protocol activates, Lumina goes silent, and he is trapped with specimens that no longer understand mercy.
