Go inside and explore

You enter the building - it's a cool and somewhat dark corridor after the warm day outside. Passing a few empty rooms, you start to explore the huge old building with its maze of rooms.

You reach nearly the far end of the building without being spotted, to a kitchen area where a door leads out to the courtyard. The scent of a barbeque wafts in from the outside.

Behind you is a staircase. Cold concrete steps lead down into what you can only assume will be a dungeon.

There are some more rooms nearby, including what looks like someone's bedroom.
