Past the entryway is a longer hallway, with mailboxes lining the sides [check the mailbox post for further description]. At the end of this hallway, finally, is a door with a window on it.
And passing through the door, the atmosphere changes dramatically.
It opens into a grassy area, with various buildings set throughout, almost haphazardly. You take note of the fact that there are more doors set in the 'wall' of the compound, and come to the realization that the walls must be incredibly thick. And that there aren't many windows, either; only in the buildings within the compound are there any windows anywhere.
The buildings set within the compound are tall, and there are stone paths that lead throughout. While there seems to be no real pattern to the layout, you notice that there is a building set in the very center, with a (shorter) wall around it. The gate there, however, is closed. And locked.
You can catch sight of what looks like a more low-laying building through the gate, but other then that, it remains a mystery.
