She could feel her back getting wetter as it was pressed against the slimey wall. Her smart black jacket absorbing the slime. She shifted away from the wall, still feeling weak, that was about all she could do. She lay on the hay for a few moments, her face only inches away from her high heels still so shiny even in the low light of the dungeon.

Eventually some of her strength came back and she pushed herself into a sitting position, she couldn't just sit here for ever.

She examined the chain, had she managed to weaken it at all? She traced her bare hands along the cold links. All of them strong, and all of them unbroken. Zatanna traced the end of the chain to the wall, it was attached to a giant metal ring that was embedded into the stone. She then traced her hands back the length of the chain to find out how it was attached to the collar. There was a small ring between the collar and the chain, this could be a weak spot.

It was then she felt that there was writing on the collar. She tried to trace the shapes with her fingers. They seemed familiar, but without being able to see them she couldn't translate them. If she could write the shapes down she might be able to work out their meaning, maybe they'd contain a clue to what this collar was and maybe how she could escape. She patted down her jacket and waistcoat looking for anything she could write with. Finding nothing she looked at the slime, she could write in that, but what with, she then looked reluctantly at her high heels. 

Picking the heel without her gloves in it, she picked it up, and with one hand at her throat Zatanna began writing down the symbols into the slime on the floor.

It was time consuming, and got difficult around the back where her hair over hung the collar but it was something to do. Something was much better than screaming or sobbing. 

Eventually she sat back and looked at the completed symbols.
