“ The Wizard-Brewers of the Old Empire stored memories in bottles of mead, passing their brightest ideas, most subtle magics, and most important decisions on to their heirs in bottles of oddly-flavored honey-wine. A cache of these ancient magical vintages has been unearthed, but does anyone dare drink from it? The ancient mead's creator is a complete mystery, as are the thoughts he left behind.”
“ Sages and naturalists frown at the common name given to these strange creatures by the small folk, but sometimes the silliest nicknames for creatures, places and people persevere in the minds of many. 'Purifiers', 'Pond Jellies', 'Breath-Stealers', 'Lung-Ticklers' and 'River Butterflies' are much less commonly heard appellations for these life forms. Wet Faeries are basically (and simply) a species of fist-sized, fresh-water jellyfish. Several traits steer them toward the peculiar category however. Firstly, Wet Faeries are nearly invisible in the water, much like their marine cousins but even more so. One can swim in a river swarming with these critters and not even notice their presence. Secondly, they possess the unique ability to clean and purify whatever body of water they inhabit. They do this via some sort of biological filtration process, sucking in all toxins present in the water, and releasing it back in its purest form. Needless to say, they are both a blessing and a curse to whichever folk dwell beside the rivers and lakes Wet Faeries inhabit. On one hand, no purer water can be found anywhere than a Wet Faerie lake or pond, and yet, in 'pure' water 'life' tends in fact to die out, lacking the needed nutrients to prosper. Thirdly, their 'sting' is (unfortunately) virulently poisonous to all mammalians. Wet Faeries are loathe to sting anyone or anything, using their barbed fronds as a last line of defense, but if stung, most swimmers will suffer respiratory arrest, and die within minutes, usually drowning before they can make it back to shore.
Alchemists, druids, and less savory characters have studied these creatures over the years, and have predictably found all the ways Wet Faeries could be exploited. Morbidly humorous, some bards find it, that the Poisoners and Assassins Guilds as well as the Healer's Union, all prize these creatures. The assassins use the extracted venom in obvious fashion, while the priests and healers use the still-living jelly-fish to sterilize other poison potions and to cure those already poisoned on death's door.
It is known that a certain Earl Von Trumble keeps his vast castle moat stocked with Wet Faeries, the waters so clear that every bone of every one of his past enemies can be clearly seen on the bottom, twenty two feet below.”
“ A modern kingdom still strictly adheres to ancient traditions due to their long forgotten deity getting annoyed at the moral decay, appearing as an AI Singularity and forcefully correcting everything it sees as morally wrong. As such, even though the weapons and technology have improved, the culture hasn't.”
