Night 9: Battle Hymn
Welcome to the Ninth Night of the Darkest 13 Nights of ChristmaHanuKwanzaakah. The prompts have no deadline and can be combined with past challenges as well; don't feel as if all works have to be posted before the next prompt is given. Any work (even light-hearted ones) is welcome for this challenge. Fics are not the only works that can be posted; art, discussions, icons, and anything else are welcome.
The ninth prompt is battle hymn.
Remember: All prompts can be found on the prompt table.
