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?”
“ A slow, stupid creature that crawls onto people and latches onto them, often on feet, hands, and other extremities, numbing down the area and slowly feeding on it. It's easy to avoid while awake, but nearly impossible to remove once attached. Many an adventurer has been forced to hack off an arm or leg after waking with a Stoneleech wrapped around it. Sleep with one eye open! (This idea came from 'Wizard's Rule')”
“ In the far reaches of a long-lost wilderness, there stands a forgotten town inhabited only by children. Though they appear normal enough, their eyes burn with madness, and they speak in a foreign, archaic tongue. Nearly a millenia ago, a powerful spell had gone awry, or maybe it had succeeded - in any case, it ended up blessing, or cursing, an entire generation of children with agelessness. However, as the centuries passed, the children's parents grew old and died, the buildings of the town crumbled to earth, and even the civilization itself faded into history, becoming lost to time. All that remained were the children, driven mad by the psychological toll of living for hundreds of years beyond their age. In time, most children died, killed off by fighting amongst themselves, while many others were driven to suicide. Only a small handful remain, and they are a strange people indeed.”
