Writing a dialogue based on a picture

Ciana walks into Celeste's messy room to find Celeste, working hard on her novel. Her room is littered with balled up pieces of paper that Celeste crumbled up after failed attempts of continuing her novel. Piles of books are all over the bed and the table is stained with drops of coffee, slowly descending down the cold mug Celeste has been drinking from since morning. The mess really annoys an already upset Ciana.

Ciana swings the door open and finds Celeste working on her novel

Ciana: (pointing to the floor) What have you made of this room?

Celeste: I am very busy right now Cia, I don't have time for your taunts.

Ciana: (Realizing her sister isn't paying attention to her) Jeez, calm down Celery. I was just joking. Anyway what are you working on?

She slowly walks up to her sister and grabs the notepad

Celeste: Give it back you jerk.

Ciana backs away and slowly walks over to the window.

Ciana: (quite upset on how her sister acted) Mom just shouted at me for wasting my time trying to get into Art school so I just wanted to come here and talk to you, guess I shouldn't have.

She hunches over and covers her face with her arms.

Celeste realizes that she made a mistake and tries to walk over to Ciana.

Celeste: (Tapping Ciana's shoulders to get her attention) Hey, wanna hear a story?

Ciana: I am not five anymore Celeste, and this is serious.

Celeste: Fine, I get it

Celeste: So I guess you don't want to hear about the Castle of Lord Westbrook of Allfor that my friends and I were talking about in the coffee shop today.

Ciana slightly lifts her head up almost hitting the window handle

Ciana: (Hiding her excitement) Well where is the Castle of Lord Westbrook of Allfor and what is so special about it?

Celeste: It is a medieval castle made in the year 1245 by Lord Westbrook of Allfor. He was the nephew of the king and therefore inherited great wealth from his uncle. The story goes that when the king was overthrown and all the noblemen loyal to the king were mercilessly killed, Lord Westbrook provided shelter in his castle to a lot of people and when he was killed, the looters never found the castle. Legends say that anyone in danger who seeks refuge will find the castle where it's least expected. A lot of people claim to have seen the castle when in danger.

Ciana is very intrigued by this and asks her more questions

Ciana: So what exactly does the castle look like, you know in case I am ever in danger and this structure appears in front me, I need to know whether I should go in or not?

Celeste: (Partly laughing) Well first of all, it doesn't just appear, you have to walk a bit on the road till you see a tower made of grey stones.

Ciana: Well thats stupid. If you have to walk to get to the safe zone, wouldn't the danger, whatever it maybe, catch on to you?

Celeste: You are right Cia but here is the thing, people say that when you start walking on the road, you will disappear to the thing that is chasing you, be it an animal or a human.

Ciana: (looks down and sighs) Does it give refuge to people with mothers that crush their daughter's dreams and feelings?

Celeste understands her sister's worries and tries to comfort her.
