Elias found himself sitting in the boss room, right after passing through two tests, while everyone else had to go through a myriad of life threatening tests to reach the room with the Ice Phoenix Flames.
It was truly a place created by a gambler where luck reigned supreme. All he had to do was walk through the mirror to enter the final room which others had to fight with their lives to reach.
There was only one problem with the final room. It was that the room was filled with corpses that belonged to the seniors that had the highest chance of succeeding according to the Dean who sent them here.
The Seniors didn't have any wounds on their bodies. There were no signs of fighting either. It was more like they had just died out of nowhere after reaching the final room.
In the final room, there was only one person who was still alive and standing on their feet. But that person didn't belong to the Academy.
