Looking about he sees that indeed the only feature on the first floor are the stairs going up. They appear to lead up 20 some feet along the inside wall and end at a door. Whatever floor is up there, the ceiling could not be more then 15 feet or so before it would hit the ceiling on the roof. Neville does notice what might be an uneven stone in the floor near the stairs – possibly a trap door, but there is no handle and stone is fairly large and heavy looking. There are no markings anywhere within the Tower, no chairs or furniture or even dirt for that matter.
