Thunderbirds are enormous birds found throughout much of Zhu Province[75, 17] in the Krasarang Wilds. They can be found perched atop high cliffs, nestled in the thick grasses, or flying overhead in flocks. Yi-Mo Longbrow, in the depths of his despir, lays himself on the ground in the northern part of the Province in hopes the birds will devour him.
The thunderbird features in Native American beliefs. In one variation, they are the harbingers of storms; as the Wilds are in a constant state of rain, there could be a loose connection to this belief.
