Once Hade and Quinn concluded their excursion of the First Imperial School on the rooftop, they discreetly returned to their dorm via the spooky tunnel.
On the way back, the old hallways were as quiet and as bright as ever, but, the shrewd duo still made certain to maintain their caution and discretion. After all, you could never know who was watching behind the scenes.
Fortunately, judjing by the lack of professors waiting to apprehend them, it seemed that their escapade had not been discovered as of yet.
Upon their successful and most importantly, uneventful return, Quinn told Hade that he was free to make the rooftop quote, "his safe haven," and that it could serve as their very own covert hideout... like that of a secret club.
Hade only agreed because he felt too tired to argue. Afterwards, he made himself familiar with their resident dormitory training room.
