Oazduke's Vengeful Head.
The head haunts all headsman and executioners.
A floating, bloody head, long separated from its body, is a particular legend among a very particular group of people, executioners, specifically those that chop heads from a block for a living. It was that infamous highway robber, Oazduke the Vengeful, who when finally captured and put to the axe, screamed his foul hex, seconds before his head flew off.
"You will know it is me when I'm through
A curse on your ilk and on you!
May my severed head haunt you eternal
Frightening you headsmen infernal!"
Years later, not one but two(!) weary, puffy-eyed, spooked, headsmen, haunted day and night by Oazduke's insufferable severed head, approach the party cleric in order to hire him to exorcise the ghost head once and for all.
A PC Conjurer or summoner, basically any mage whose sole purpose in life is summoning creatures to aid in battles and various situations, is cursed with a hex, and needs to find a way to undo the curse...before he goes mad, or his fellow PCs throw him out of the party, or worse.
Everything he/she summons, never goes away. So you'll have to figure out what the heck to do with that dire bear or fire elemental once it's done fighting the orcs for you. Eventually a caravan of bizarre creatures either annoyingly ends up following the summoner around, or they go off to cause mayhem elsewhere. Bad news for the poor spell-caster regardless.
One day a a wind begins to blow out of the West. The next day it gets stronger. And stronger still the next few days. Eventually (and fortunately), the speed of the wind tops out at a steady fifty miles an hour, but continues to blow. Soon an entire kingdom is wondering why it's not abating. The weather mages deem it unnatural but can't seem to banish or control it. The priests of various faiths claim it's divine. The End-Of-Days crowd is having a field day with their predictions of doom. No one knows why the gale persists. When inquiring with neighboring kingdoms, it seems they too suffer from a persistent western mistral. Eventually the populace begins to adapt to living with a twenty four hour a day wind. Always from the West, and perpetual. What could be causing this? A raging Elemental king? a curse from the gods? an unearthed artifact? Or has Nature itself gone haywire?
The old clock tower stands tall, but the bulk of the uppermost storey is crumbling and unsafe, with gaping cracks in the walls. The metal struts and girders supporting the great bronze bells are still intact, though, and the bells survive. The grotesque gargoyles and arabesques which decorated the original design have either fallen into the street (once or twice a year more bricks fall from the tower, prompting calls for its demolition) or have been defaced, but the main doors to the clock tower are still intact and show signs of being kept in working order. This is the home of The Captains, clad in raggedy clothes, with sooty faces, and perpetually runny noses. But behind each set of eyes is the look of a survivor. They live to stick together and make it through each day. Older than their years in many ways, the friendship they share with each other and Wims ghost keeps the core of a childs innocence and hope alive in each. But they are still very suspicious of outsiders. They are a group of street children who live in the clock tower. Some are orphans, some runaways, and some nomads who occasionally return to their homes. But they’re all poor, dirty and perpetually hungry, as well as being wily, unscrupulous and mischievous in a fairly brutal way. Enough of them have suffered at the hands of adults for all of them to be wary of any grown-ups, particularly ones who ask too many questions, although with hard work and a lot of food it might be possible to win the confidence or even the trust of a few of them.
