Holy cow, that is a good idea! Yes, the faeformers get together to coordinate their activities/stuff they do so they don't clash with each others, and also because some of them can't stand the sight of the other. But there is one day where all of them gather to have this huge party, going all TGIF. xD They dine and go drunk on magical wine, and dance to music played by the fossegrim bc let's face it, some of them loveeee dancing :D
Yes! :D One night every year all the faeformers from the different courts get together and put aside their grudges for one night and just freaking party! It’s loud and wild and fun, and above all safe because it is an unspoken rule that you Do Not harm another faeformer during the truce period. (To do so would invoke the wrath of the ruling fae, and possibly even death.)
It’s considered especially dangerous for humans to go wandering around outside during this particular night. Especially with so many of the more dangerous faeformers lurking about. (Most people living in the nearby villages cover their ears to block out the strange, haunting music and huddle together until morning.)
Of course, there are humans who either ignore the warnings or simply get lost in the woods at the worst possible time that happen to stumble across their fete. While the faeformers are forbidden from shedding any blood (including human blood) for this one night, be very wary as some of the more unscrupulous ones will try to trick you into staying with them forever. Stay and dance for a while if you must, but whatever you do, make sure you don’t eat anything they offer you and that you get back home before dawn.
