A Shadow over Akeroth
The Great Green expanse that stands upon the edge of Akeroth. Yseria is the Domain of the Druids and the Dragon Aspects and a great, thick mist shrouds the lands beyond the foothills. Only those welcome or Brave (or Dumb) enough to fight it ever enter, and those that do rarely return.
Yseria is purported to be a venerable paradise that exists on Akeroth, and it is because of this that the Druids and Dragons guard it so fiercely.
