WiP Haffun

A city that lives in legend for most of the inhabitants of the Kingdoms, Haffun is the only major settlement in the Teng'hari to have survived to this day. Reason for this, is that an invisible aura envelops the city and much of the land around it, and all who enter, fall under the Barbarian's Lament . How has it survived this long in the central wilds? What keeps the blessing going? Where did it originate from?
