Jenny Everywhere's staff

In the Collapsed Cosmos, when faced with the necessity of dueling Laura Drake, the “collapsed” Jenny pulled a collapsing staff from her jacket pocket. Pressing a button on the side, she was able to expand it to its full size; vibrating in her hands, it began to glow “an eerie shade of blue”, and proved a match for Laura Drake's sword.

Later, during her trip through Faerie, she used it alongside her light-knife while fighting off the Wild Hunt. She displayed the ability to vault using the staff when it was at full size. (PROSE: The Hermetic Garbage of Jenny Everywhere)

Behind the scenes

The description of the “collapsible staff” is reminiscent of a lightsaber from the Star Wars series.
