The feeling in the shop would be... calm. Supernaturally so, really. The air was clean, the sensation light, almost sleepy. The light filtering in, while not brilliant, had taken on a hazy, almost rosy tint. Full noon it might damn well be, but for just a moment, it'd feel more like a summer twilight.

It wouldn't be hard to follow him, at least. As the shadows grew longer in the back of the shop, the light of the archangel's wings grew all the brighter, casting an otherworldly, cool blue glow across the books. The rustle of feathers gently skirting across the floor and past book shelves, the gentle sensation of the air in a church yard after a thunder storm.

Azrael was indeed well aware at this point that he wasn't going to remain unfound for long. He'd speak moments before he could be seen, not wanting to startle the other angel too terribly.

"I apologize, for not using the door properly. I fear I'm not quite in any state for most humans to see, yet."
