Who are you!?

"Welcome to the third and final test," a young man with long black hair and a scruffy, unkempt beard said. He looked to be in his mid-thirties, but he wore a white robe, signifying that he was an outer court sect master. 

He had collected the examinees from the plateau and led them further up the mountain to a long building with a tall roof. It was large enough to fit over one thousand people inside, but with the one hundred and thirty or so examinees, it looked empty.

A stone platform with intricate overlapping runes drawn into the floor stood in the middle of the room. The other four sect masters sat on thrones on the stage, looking down upon the examinees. 

"You will form a single-file line. The order doesn't matter, as you will all be called up. When you are up here, you will display any secret skills or abilities you may have. Don't hold anything back, as your admittance into the sect may depend on it."
