Herr Brackhaus: Leaving the tenement undetected is trivially easy for you, and when you approach the ruined department store nobody seems to react to your presence. You get about twenty feet away from the western wall and get a good look at the fire-escape. It looks like the ladder, which would normally be on the southwestern corner, has been torn off. It looks like either an impossibly strong person tore it away, or a vehicle hit it or something. Or perhaps an explosion. Either way, the metal is badly twisted and jagged. A remnant of the ladder still dangles from the southern portion of the fire escape, but it's twelve feet off the ground. You'd need a boost or a mighty jump to catch it. You could climb the western wall again, but it's made of smoother material (sheer plasticrete) than the tenement and harder to climb, and you're more likely to be seen (you'd be visible from the street doing so).
Your Perception check is good enough to tell you two other things: whatever damaged the fire escape also pulled it loose from it moorings on the southern edge. It's almost imperceptible, but Fenris can see the fire escape gently "swinging" and rattling against the building in the breeze, as it's only attached by its northern pegs. It would require exceptional balance to climb up onto the escape and prevent it from swinging and rattling wildly, causing a racket. It's also possible that too much weight would cause it to collapse entirely.
The other important thing Fenris notices is a security camera above the fire escape, set between the two windows. It seems like it has a limited view of the street and the western side of the building, and a very good view of the fire escape itself. Fenris doesn't have any significant security insights about the fire escape, though the presence of the camera suggests whoever designed this place knew it was a security risk.
Irn0rchid: You can go ahead and consider it about 8 PM; by the time Fenris is done sneaking up to and away from the western edge of the department store, it'd be about 8. Earlier you had a Security Design / Knowledge check with 4 hits, right? Now that she can see the target for herself, she comes to the following conclusions:
-This place used to be a department store, meaning it probably had some security cameras, maybe an on-duty security person, and probably some type of threat response team. It's Redmond, so probably not KE or Lone Star, but somebody. That was when it was an active business, of course. Now that it's a ruin, you probably only have to worry about surviving security cameras. You wouldn't be surprised if one or two doors were reinforced, and it might have an old safe somewhere for credstick transactions, but that's about it. Commercial stores in general are pretty soft targets, tending to rely on light security and fast response times from law enforcement. This place might be a little more self-sufficient since it's out in the Barrens... knowing when this thing was built would be pretty illuminating.
-Of course, this isn't quite a normal department store. It's a bombed out ruin of a department store that has had squatters and gangers sitting on it, which gives it all a sort of "wild card" edge. Security systems you might expect to be there, like simple locks and cameras, might be damaged or ripped out by looters. On the other hand, you might run into jury-rigged traps you wouldn't expect. Tough to say.
-One thing you know for sure is that Red Wormz are gangers, who like to travel light. They probably haven't done any sort of serious fortification; that's not their style. Fortification costs nuyen and leaves behind evidence. You'd expect security counter-measures to include informal patrols and light traps and alarms that can be easily cleaned up, hidden or re-purposed in case of a KE raid. Those would be her best guesses, anyway.
Feel free to incorporate any or all of these insights into your next IC post, and go ahead and assume it's 8PM or getting there at this point. Nothing specatcularly interesting happens to Kynos and Fenris in the interim, unless they decide to start shooting or whatever.
