Clara Island's castle was not overwhelmingly huge, but it was by no means small, with the main fortress being somewhat larger than the one belonging to the Lap School on Blackstone Island.
However, the underground of the castle was exceptionally cramped, totaling only about a hundred square feet over two levels.
The stairs leading to the second sub-level were securely sealed off by restrictions, making direct descent impossible and obscuring vision to prevent one from glimpsing the specifics of the second level.
But Colin surmised that below was likely where the defense hub of Clara Castle was housed.
Turning into the first level, the space of over a hundred square feet was simply divided into two rooms, connected by a corridor on the far left.
At that moment, Mill stood in front of the door to the first room.
"Good evening, both of you."
"Good evening, Lord Mill," Colin and his companion bowed.
