Fenris
As Fenris circles around to the back side of the department store (careful to stay out of view of the camera he spotted on the western wall), he sees the uneven ground and the back door he recognizes from the surveillance. This entrance is the only actual door to be found on the exterior. The main entrance was presumably on the now-destroyed southern and eastern walls; this was just a back door that had long ago lost its "door." Now just a hollow door frame, Fenris could see a tile floor inside, covered with gravel and rubble. It led further into the shadowy interior of the department store ruin, and he could see metahuman forms moving further inside.
Robin
The black void of the astral overwhelms your senses as your gaze slips from the physical world. You of course can't see through the walls of the department store and into the second story, but with the southern and eastern walls destroyed it's pretty trivial for you to get line of sight to the huddled mass of squatters inside. Their combined auras coalesce into one giant, confusing, swirling bloom of lights. It's tough to pick out individuals from this distance, but the overall palette is one of desperation and fear. Pretty much what you'd expect from squatters in Redmond, to be honest. What's strange are the few pinpoints of hopeful yellow and intensely curious orange-pink scattered throughout.
After studying the mass of auras for a while, Robin is able to confirm that there about two dozen metahumans in there. Mostly trolls and orks, with the odd human thrown in. They're in varying levels of health, with some very ill, others perfectly healthy, and plenty in between. Over time, he detects two auras that stand out from the rest of the group; these ones are sizzling with a nervous maroon energy, the kind Robin has over the years learned to associate with braggadocio, or people acting tough when they don't really feel all that tough. These two weird, slightly paranoid-feeling auras are the only two with any discernible 'ware; one toward the very back of the building seems to have some light headware, probably cybereyes. The other, standing at the forefront, appears to have cybereyes too, along with some light internal 'ware on his kidneys, where one would expect a nephritic screen or toxin extractor to be.
Noticeably, Robin doesn't spot any lurking spirits, wards, or other obvious astral security.
