"Celia Remains 01"

In the audio titled "Celia Remains 01", the prominent sound is that of a door. The door is not an ordinary one, but an automatic one, which can be deduced from the mechanized hum that accompanies the sound of it opening and closing. The audio starts with the faint whirring of the door mechanism as it begins to close. As the door progresses to its closed state, the sound grows slightly louder, indicating that the action is nearing completion. The distinct thud of the door securely closing punctuates the entire audio. By the end, the listener is left with the understanding that the door has been completely shut, and the silence that follows suggests a sense of finality.
