Diagnostic

In a broad, expansive dome-like area, a massive door automatically opened from a tunnel, and from that tunnel emerged an entire group of young adults not in their usual uniform, led at the head by a tall, tanned, smiling man. 

As they entered, they were dazzled by the blinding light, before the entire room came into view… 

They all felt utterly dwarfed. The dome itself was the size of dozens of football fields and spanned hundreds of meters in height. The walls were black with purple tinges, matching the entire aesthetic of the school, rows and rows of benches were seen all around them protected by a green energy dome keeping off any possible attack at bay, of course completely empty.
