Gorefang Bounty

Before the rise of human plantations tended by gangs of the dead in Fehr Volgi, the elven tribes that roamed the western ranges of Rynabor had to contend with a violently verdant wilderness. The same necromantic polarity that powers armies of dead slaves today once fueled a raging horde of beastkin, or orcs as they are more congenially called, and the rich wilderness that sustained their ravenous appetites. This lush land was once home to great herds of yaks that drew in the orcs, who themselves had been driven west and north by elven hunting parties.
When the wild herds had been wiped out and the forests stripped bare and charred by the booming population of green blooded tuskers, their progenitors, the elves, had become so appalled by the destruction wrought by their folly that a bounty was offered. What better solution to thin the populations of two enemies than by incentivizing one to declare war on the other? Each year for more than a generation of the little ogres, emissaries of the elven clans were sent to the lords of the rebel human lands west of the Boranes Divide. Rich payments were promised for each pair of tusks presented, still attached to the jawbone, known as the Gorefang Bounty. Orcs could recover from grievous wounds that would end a precious elven life, but without a jaw or tusks to sustain them and proclaim their status even the most ferocious boar or sow was as good as dead.
The little ogres proved more resilient and resourceful than the elves had anticipated in their campaign against the orcs. The groves around elven settlements became festooned with grim wreathes of their kins' shattered jawbones. With the resources paid through the Gorefang Bounty the humans not only drove the beastkin from the verdant lands the elves had hoped to reclaim for themselves, but established settlements of their own. Through their temptation the elves founded a vile new human realm, powered at first by the labor of the jawless animated masses they had commissioned.
