THE SECRETS OF THE ANGEL OF WATER

That night, Castiel sat in his allocated room, holding onto the leather bag that he had carried off from the angel realm. The soft flicker of the candle light cast long shadows across the stone walls of the demon castle. 

Of course, being an angel, he had never been so deep in enemy territory before, but the castle was everything that Castiel had thought it would be, perhaps even more. Since it was night, it was eerily silent, save for the distant hum of creatures that lurked in the night. Most of the sounds Castiel did not recognize, and he decided it was better to stay cooped up in his room than go out for a walk. 

There was a faint scent of something sweet clinging to the air, mixing with the lingering warmth of the day's sunlight that had seeped into the dark stone.
