At the corner of air and earth elemental planes resides the dust Elemental, a growing threat to Parisia. With it's powerful choking attack, this creature is a threat to the city. More and more of them are appearing in town, spawned from the many dust devils, a frequent foe of the party, they come in size from 3 HD to 20 HD. Why are there so many? Why in the city?”
“ The PCs are making their way from village to village across a rural hinterland, when they spot a weird sign along a farmstead's fence, with an arrow pointing to the actual farmstead.
'CRAZY DANCING HOES!!'
If they investigate, a rather sedate local farmer, explains to them that for a mere two coppers, they can witness the show for themselves.
The show involves six ordinary, animated hoes 'dancing' on a makeshift stage, as the farmer accompanies them by slapping his thighs to keep the beat, and playing on his flute.
If asked how the trick is accomplished the farmer demurs, not wanting to share his 'secret'.
'If you can get Old Man Purkiss to tell you how he gets his cows to spout poetry, I'll tell you how I make my hoes dance.'
In reality, this minor encounter can lead to the PCs discovering that some localized, magical effect is active in the area. All kinds weird phenomena seem to occur in these parts.
Perhaps the PCs have finally found the ley-line of mana energy that they have been searching for! The party's wizard gets excited.”
“ The PCs come across a town with a strange curse: Every morning, those who have grown up here wake up with the memories of someone else. They do not find this strange and have no idea it is happening. They calmly wake up and start these new lives as though they have always been that way.
The cause: A wizard who lived there was spurned by a maiden he was infatuated with. His attempt to manipulate her memories into believing they were already together and that she loved him went horribly awry.”
