Rainbow Undecimber

The Rainbow Undecimber (무지개빛 십삼월, Mujigaebit Shipsamwol; "Rainbow-Colored Thirteenth Moon") is one of the 13 Month Series created by legendary craftsmaster Ashul Edwaru for the Princesses. It has never been granted to a princess. Instead of a needle or a hook, the Rainbow Undecimber is an arms inventory.

Notes and Trivia

 * Contrary to what some may say, the word "Undecimber" is correctly spelled with an "i". In calendar sytems that have twelve months, a thirteenth month, were it to exist, would be called "Undecimber".
