The first hallway that Seph stepped into would be the one the one that houses the old prison, which at current only has one prisoner, Berserk. The passageway would be dark, moldy, and rather depressing, being that Jenna only bothers to minimally light the level.
As Seph travels farther into the cooridor, he’d here a loud clanking sound followed quite frequently by an even louder smash. After each of these loud bangs, there’d be the wobbling of reinforced glass and a soft screaching noise. Also, at times, feral snorts and growls would fill the hallway and echoe off the walls, most likely making the area even less inviting than it was before.
