A hunchback answers the door

After knocking you wait seven minutes. You are about to turn around and walk on when the door opens with a loud grinding of aged wood. A hunch backed dwarf in a greasy black hood is standing there holding a lantern shaped like a owl. The storm roars worse outside as he beckons you in. It seems this man cannot speak, only make dumb mumbling sounds. You follow him down a cold stone hallway.
