"A trapdoor? What is this?"
Arthur knew a trapdoor would lead to an underground area, but what could be down there? He was expecting some kind of basement, but what he found was something incredible, and also unexpected.
He opened the trapdoor and went down through a staircase. Then, he saw an entire underground area with many buildings, libraries, shops, and anything one could imagine.
"Is this the real school?"
The students of the Blood Spear school lived in the underground. Arthur sensed nothing at all back when he was on the surface. A magical barrier protected the underground from not only attacks, but from scouting as well.
One of the impressive things Arthur saw down there was the roof. It was translucent, meaning one could see the sky from the underground, yet anyone outside would see nothing.
"Impressive work!"
Almost all the students were asleep, but some stores were still open, though Arthur was not sure if he would want to explore it.
