“ With a huge number of sacrificial victims, another realm long ago secretly bound a Prince of the land spirits, Iorstonn by name, thus ensuring the fertility, and improving the magical defences, of their realm. But binding that Prince to one spot has disrupted the weather and magical patterns (ley lines?) over half the continent. Things have become bad enough that a coalition has been formed to rectify the situation, once divinations have established the cause.
Your party is one of the teams assembled to do the rectification: find the binding object and steal it ('so that we can destroy it here in our realm, of course'...*) or destroy it over there. Presumably the Prince will be grateful to his rescuers and angry at the binders, but with a greater spirit like Iorstonn one can never be sure: such beings are 'tricksy'.
* Of course, the rulers of our realm might want to control Iorstonn for their own ends...”
“ During a public holiday in the small town of Wyrmbersch, the Mayor is accidentally killed by a statue which falls from the roof of the Town Hall. As shocked spectators crowd around the body, they discover that the Mayor, at the moment of death, shape-shifted into a squat, stunted humanoid figure, it's grey skin dominated by bony ridges and lumps. How long was the Mayor an imposter? And who else in the town isn't what they seem to be?”
“ Draw the party together as debtors to the local lord, king, head of the thieves guild, or mercenary clan, who is forcing them to work together to pay off their debts.”
