Breathing. The sense of breathing would be the first thing to return to young Brandon, and soon all the senses related to it. The air was humid, or on second thought smokey would be a better description; clearly something was burning. As the sense of smell returned the nobleman would get the feeling that much of what was in the air was incense, but many fouler smells yet indistinguishable would also fill his nostrils. The lad was lying on some sort of steps, the cold and somewhat wet stone digging into his skin. A ghastly susurration would fill his ears and upon opening his eyes it would seem to be coming from the smoke about him. Coils of it would form shapes that in the first moments of consciousness would easily be mistaken for faces or skulls both proper and mutilated, malformed. It was a crypt of some sort, a great many steps leading to a rectangular block of stone that may have been a platform for embalming, or perhaps a coffin, or maybe an altar of some sort. Regardless of what it was, a trail of sickly black blood along the steps leading to the Unicorn would be simply evidence that he had fallen and rolled off of it. 

Through a strange green lens Brandon now had it would be easy to see the room was poorly lit by the few candles in it, the globs of filthy wax appearing to only accent the darkness rather than provide light. The thing that really allowed him to see was a flame spreading across many books and corpses in the building, the fire yet too small to reach the banners across the walls. It was slow, the occasional fiery bursts of corpses' gases or fats not doing enough to counteract the cold and wetness of rot and blood. The stench was terrible, worse than anything the Lordling would have previously dealt with and yet somehow bearable. If he chose to stand up rather than rest the many pains he would sense across his body, it would be clear that all witnessed to this moment was more or less the full extent of the building. The only new thing revealed would be the exit, a very long thing from which some helping light both natural and not would come. If he paid attention, the noble would hear voices and the clank of plate armour coming from there (albeit getting further and further away).

Though the fire was spreading slowly - almost leisurely in fact - there was an ever so slight sense of urgency given by a rumble from below. It didn't signal that the structure was going to collapse soon, but rather that there would soon be bigger rumbles that would signal this. As the lad would now have to choose what he would do next, memories would start to flutter into his mind.
