“ In a certain nation, no-one except the Emperor is allowed to have a name. Therefore, the people give themselves pseudo-names called 'callings'. Examples of callings: A family is known as the Red Sparrow family. The father is called Swooping Red Sparrow. The wife is Bright Red Sparrow Blue Lizard because she was called Bright Blue Lizard before marriage. Their daughter, until she becomes an adult, is Daughter of Red Sparrow. Their sons are Eldest Son of Red Sparrow and Younger Son of Red Sparrow.”
“ Once every decade on the eve of St. Poskov's Day during mid-winter, the coastal city of Tiyabon experiences a horrific event. Quool's Tide rolls in, depositing hundreds of bloated, fish-eaten corpses upon the pebbly shores of Tiyabon's wide bay. This singularity is to this day unexplained, though countless theories abound. It is said for example, that these corpses are not eaten by the myriad fish of the seas completely, due to the fear all creatures of the seas hold for Quool.
Named for Quool, a terrible, antediluvian god of seas and storms, who no longer exists for he has no worshipers, the Tide chokes the beaches and surf with the countless rotting bodies of those who had perished at sea in a violent way.
Almost immediately, the lifeless corpses are fed upon by crabs, gulls, and worse things that await the horrid feast. The townsfolk let nature take it course with disinterested disgust, though lately some enterprising adventurers have taken to searching along the beaches of flesh for former deceased companions, with intentions of raising them again!
Surprisingly no undead ever rise from among the many corpses. This is also a mystery.”
“ 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...”
