“ Castoria was once a thriving and prosperous nation, a rich trade center for the surrounding lands. This all changed when, on one fateful night nearly a century ago, the Mist of Eternity rolled in and surrounded the land, obscuring more of the outside world as days and nights passed.
By the time the Mist blocked out the sun, a new light shone during what was assumed to be daytime: The Starpoint Spire, a mysterious place atop Castoria's highest peak in the northern-central region. Some say that there is some sort of building atop the mountain shining the dim 'sunlight' onto the land, but it is only ever too bright or too dark to fully make out any structure, not to mention the mountain's immense height.
Not a month after the Spire's light lit up, the stars fell. Flaming rocks and debris from far-flung edges of space plummeted downward onto the eastern region of Castoria. Once the shower subsided, a strange energy from within the fallen stars transformed the eastern lands in what are now known as The Voidwastes, a barren gray land littered with craters and strange alien creatures (these can vary, but I had Pathfinder's Akatas in mind).
To the south, strange mechanism of eldritch origin are again at work after aeons of rest in the Ruins of Kchuthngnl, an ancient city of non-human creation that is estimated by scholars to be no less that five millennia old.
To the west, the once peaceful and serene forest, now known as The Plagued Woods, has been experiencing corruptions of the wildlife and humanoids living there. Some humans have reported creatures that appear not unlike a halfling, except that they can open their mouths to massive proportions to swallow creatures the size of an ogre.
When adventurers and citizens alike try to make an escape from Castoria, they are never seen again, and it is utterly unknown whether they found hopeful sanctuary or agonizing death withing the Mist's depths.
What is unknown to all residents of Castoria is that all of these events occurred because of the actions of a secret but powerful cult loyal to the Elder Gods who call the space between the planes their abhorrent home. The cult still lives on, larger than ever, and their plan is for the alien horrors to incubate and thrive within the dome of mist that now envelops Castoria, so that when the Elder Gods return as the cult's prophecy foretells, they will have an army of blasphemous creation at their disposal that they will use to make war with and enslave the denizens of the Material Plane.”
“ 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 caravan is traveling through the desert. The party is hired to capture a man who is in the caravan, and it must be done quietly, so that nobody else knows. They are given the man's name, and the fact that he is a mage, but no other information about him. The catch is that the caravan consists of ten wagons, with at least thirty or forty guards.”
