What is Foxfire?

[DaisukeKaiser]

The title is basically my question, I've been curious about it for awhile and no matter where I look online I can't seem to find a concrete answer and given that kitsune are a highly discussible topic here. I thought I'd ask and see if anyone either knows or has theories to what it truly is.

It is, in D&D 3.5 terms, a spell-like ability.

On another tack, if you were thinking about the real-world phenomenon that's sometimes called foxfire, it's been studied and found to be bioluminescence caused by certain types of fungi in rotting wood. The Japanese term kitsune-bi covers this and similar phemomena like the will-o'-wisp, with added associations due to the specific legends about foxes.
