Containment Facility

The corridors were surrounded by cold metal walls, as were the floor and ceiling.

Many of those walls had massive, heavy metal doors reinforced with multiple complex mechanical locks and biometric scanners.

Some even had guards stationed in front of them.

Occasionally, the doors would slide open, allowing people in white lab coats to enter or exit. Some passed by Azriel and Celestina as they followed the bodyguard who had greeted them at the entrance, listening intently to his words.

"Currently, we are on Floor 0. The facility has three containment wings. Floor 0, where we are now, is the standard containment area, where we keep the lower-risk void creatures. The other two wings are underground—Floor -1 is the High-Risk Containment Chambers, where we store much deadlier ones, ranging from beast-ranked to demon-ranked void creatures. And then there's Floor -2. We call it the Black Zone.
