Attila heads up the stairs, then stops.
"Mother of Muddy Waters," she mutters under her breath, holding up a leg to stop the others.
I've been travelling with others so ling I am forgetting how to look after myself, she thinks to herself.
"Wait here and count to ten. Then follow me up. I won't be far ahead, you will be able to hear me if I shout."
With that Attila promptly disappears.
She reappears a couple of steps up. "You can start counting now," she says before disappearing again.
Attila moves up the stairs looking to stay about a landing and a half ahead of her companions; enough to keep her ahead of the noise of their ascent.
At each landing she checks the exits. If they are closed off, like the first one, she does little more than listen for any sounds of occupation and look around for any signs of recent use. If there are open exits leading into the interior, Attila has a quick look around from the door. So long as she sees nothing threatening, she moves on up the stairs.
If at any time Attila sees something that might be dangerous, she backs off down the stairs, reappears and passes on what she has found out to the others.
Assuming nothing comes up to abort her ascent, she stops at the 8th landing and after he normals checks, reappears and waits for her companions to catch up.
