“ Every now and again, the region encounters a dense blue fog. Every now and again, things disappear into the fog never to be seen again and things appear out of it from other places or world. It seems the fog is the material form of some minor diety charged with moving things around the universe to balance cosmic forces.”
“ You meet a large number of villagers, walking and weeping beside the coffin of an old bearded man (or adapt to your funeral customs). If asked properly, you learn about an old wizard, a wise man that long helped the tiny village to grow and prosper. Even after death he shows his favour: he gave most of his possesions to the poorer members of the community. All the villagers show him now respect this way. Why do you ask, are you adventurers? (As a last wish, he left a tiny case for the first group of adventurers that crosses the village).”
“ The Pcs discover an ancient, dusty oil lamp, somewhere in the bowels of a dungeon. Naturally they 'rub it', and out pops a wizened, old djinn. So far so good. Then it speaks...
'Ah at last, at last I am free! Now grant me my wish!'
When the PCs explain that they are the ones that should be granted a wish, the malignant djinn explains to them that his particular oil-lamp has a curse placed upon it. Whomsoever releases the entity inside shall be geased to grant the djinn's wish to the best of their ability.
Groans ensue from the party. The djinn rubs his wrinkled hands, grins, and proceeds to name his wish. What could it be?”
