Asherons Call: "Beneath the ruined soil of Yanshi..."

The following global message was just broadcast on Frostfell:

Beneath the ruined soil of Yanshi, the heroes of Dereth rejoice, as the brave Kishin strikes a fatal and final blow against the Harbinger. As the essence floods back through the world, an imperceptible weight is lifted from the shoulders of the populace. Peace has returned once again across Dereth.

Edit: Leafcull, Harvestgain and Darktide have also defeated the Harbinger, as has Red Monk on Solclaim, and Kittenluv on Wintersebb.
