NOTE: This was my first attempt at writing a proper story. Having seen the movie (and the dungeon scene), I just thought that a young queen with so many responsibilities might want to let it go sometimes.
DISCLAIMER: The characters of this fanart story are NOT owned by me, but borrowed from a well-known movie. This story is FOR ADULTS ONLY. If you are offended by sexuality and/or nudity and/or bondage and/or fanart that puts well-known characters into a kinky context, do not continue reading. The advantage of using already known characters is that readers already have a mental image of the involved persons, and that their background does not require a lengthy explanation.
====================
Elsa explored her bonds and gave them a playful tug. The cuffs were solid, the locks were tight and the chain strong. The ring in the wall had probably been in place for centuries. No human could escape this cell. Elsa decided to play along and tried to remember that feeling of helplessness she had experienced what seemed an eternity ago. She pulled the heavy chains, tried to recreate the sensation of despair, or the warm comforting calmness of being powerless.
Soon, she started to feel stupid, even ridiculous. The queen of Arendelle, naked except for stockings and shoes, a red stone dangling from a necklace around her neck, chained to the wall, playing prisoner like a little kid. Pretending to be helpless. Actually, not even succeeding in pretending to be helpless. Her mood changed to sadness and disappointment when she realized that this theatre play was not working, and that she would have to tell her friends that their efforts were in vain.
She decided to end this sharade and guided her thoughts to icing up the metal that bound her. She created a mental image of ice crystals growing from within those chain links, breaking through the surface and tearing the iron into pieces.
Nothing happened.
"This is distracting me more than I imagined", she thought to herself. She took a deep breath, focussed on the chain, and did her magic.
Nothing. No cold, no ice crystals, no broken metal.
