Foxfire, or kitsune-bi, glows very similarly to fire, though with an unnatural light, color, and general appearance. The flames tend to be slightly brighter, but the light extends out in a smaller radius than conventional fire would. As another abnormality: foxfire emanates no heat and is in fact chilling to the touch. This is probably a result of the fact that kitsune-bi can actually slightly drain a portion of a living being’s lifeforce.
Kitsune have the ability to create and manipulate foxfire, either by knocking their tails together or from hasty breathing. Some of these tricky creatures have also been known to transform into kitsune-bi for quick travel and flight. Also, Kitsune will often use the foxfire to deceive others, lighting misleading paths for the poor souls to make them lose their way in the wilderness.
Also of note is that a Kitsune’s Soulgem glows with these kitsune-bi, tethered in a way such that they follow the gem in the gem’s own movement. A Kitsune will at times also utilize foxfire to alter chance to prevent misfortune.
