Calyx let out a sigh as he walked past the lobby into a hallway, each side adorned with strong steel doors made to be as protective as possible, or at least feel like it was.
Along the hallway, in a shadowy corner, a cloaked figure nursed a steaming mug, their face obscured by the darkness, their motives as inscrutable as the city skyline above. He was there when Calyx left; it's almost like he hadn't moved.
Calyx made a turn into another hall, not walking too long before stopping at a door and banging on it. He didn't receive a response for a short moment before impatiently repeating his banging.
"I'm coming, damn it," Rogan cursed behind the door. Calyx didn't hear it, though; the soundproof door was doing its job of retaining all sound before swinging open.
"What?" Rogan aired his frustration at Calyx.
"I'm back," Calyx replied with a stern voice, emphasizing his words as if the information was something Rogan needed to know right away.
