Kinship Shrub is an elven festival offering that has been adopted enthusiastically by other species that hold elven elegance and refinement in high regard. After all, elves do not need to eat or drink, so the drinks that they do indulge in must be something special. Kinship Shrub is said to cleanse the palate very effectively before a great meal. What many fail to realize is exactly whose palate the drink is intended to cleanse. The shrub was devised by a particularly snobbish elf who loathed the smell of humans. When forced to sit down and break bread with them at a great peacemaking banquet, he invented this drink to lessen the assault on his senses.
The drink became popular at such feasts among both elves and humans: Elves shared the creator's delicate sensitivities, and humans thought they were being offered something ceremonial. Of course, it found a place on the menu of the Hissing Stones, where feasts are rare but difficult diplomatic conversations are commonplace.
