Extend the Story - Add a Room

Alright, how was she going to do this?

Jezirea circled the town hall, examining all points of entry. The front doors were too out in the open and not a very good choice, but she gave a quiet little cheer when she found a back entrance, away from the main street, obviously for employee use.

Now, she wasn't an expert lockpick, but she'd had a few successes.
She examined the lock on the back door for a moment, before reaching up to her braided hair. She felt around for a moment, before pulling a hair pin free from the braid.
It would have to do.

She knelt down so that she was eye level with the lock and carefully inserted the hair pin in to the key hole and felt around for the location of the key pins. Slowly, she began to turn the knob, and one by one she raised the key pins up until finally, the knob lurched, and turned all the way; the door sliding open.
Jezirea resisted the urge to cheer out loud, and pushed the door open all the way before slipping inside.

She had no idea where she should look first, and she didn't dare light a lamp as it would alert people to her presence.

She stumbled around in the dark, her hands outstretched infront of her. More than once she stumbled, stubbing her toes on something.
She made her way from room to room, feeling over the objects she could not see when finally she found what she thought was a desk, used to store documents.
She would need light now.

She stood, and searched quickly for a lamp, and finding one, returned to the desk.

She reached in to her sack and withdrew the flint, using it to light the lamp. The sparks took quickly to the oil soaked whick, and she closed the lamp, keeping it low and hidden to try to hide her presence.

She held it up slightly as she opened the desk. It was indeed filled with files.

Jezirea balanced the lamp carefully on the edge of the drawer, and began to sift through the files. She had no idea how the files were organized, or even if this was the only desk to store files. There could be desks in other rooms that contained the info she was looking for.
She continued searching throught the desk infront of her and finally gave a shout of triumph, before quieting down, remembering she didn't want to be noticed.

She had found the right file, way back with all the really old classified information. The paper had turned yellow with age.

She lowered the lamp so she could have an easier time reading and scanned through the file for the relevant information.
The sword was located in a tomb beneath Heaven's Rock.
What the hell is heaven's rock? Jezirea thought.
Obviously it was some kind of landmark the people were familiar with, but the file she had in hand did not mention where it was.
Damn...

What was she going to do? Was this landmark so well known that anyone could tell her its location, but more importantly, if she went asking about Heaven's Rock, would people know she was after the sword?
Did anyone even remember it was there?

Wait, and ask around about Heaven's Rock's location. Preferably, ask someone who is younger.
