Adrien opened the door to the stairwell of the east tower. The way up looked just the same as the other towers, with a spiral staircase that led to the door of the room upstairs. In the day, it would have been illuminated by the sunlight filtering through the large, arched windows; as it was evening, the stairwell was dimly lit by a few torches that spotted the outer wall. Adrien stepped upstairs lightly. The door to Val's room came in his sight: it was closed, and he couldn't hear any noise coming from inside, but he could see that the light was on - a sliver of light escaped through a crack down by the door's hinge. A thrilled grin appeared on Adrien's face. This was the perfect setup for him to play a little prank: all he had to do was kneel down by the hole and make a spooky noise, then hide in the corner and wait for Val to come open the door - Adrien had to restrain a giggle as he anticipated what silly face Val would do in surprise.
