Terragaia

Terragaia is the home planet of Yutaka and other characters live. The planet is located in an unknown galaxy.

Early History
Little is known of Terragaia's early history but what is known is that Ter, Ragi, Gaiaous, the Three Legendary Warlocks, started a revolution and declared Terragaia free from an unknown ruler.

Weather
The weather mirrors Earth's weather except the planet has more violent rain storms to the point that the storms last up to two weeks nonstop. The sunnier weather lasts even more well into September; it lasts from mid May to mid September. It seems the hotter weather is more brutal since Yutaka was worried that he would not have a lot to eat during those months. This suggests that Terragaia is closer to the sun; it is not to close that its way to hot to sustain life but not to far away where it is cold 24/7. This could also suggest that the winter is not so cold or brutal.

Villages
Only shown one time, it seems that they live in a medieval world.

Terrain
The planet seems to be lush in trees and mountains.

Inhabitants
The inhabitants are near-identical species to humans except Terragaians have Ka stored in their bodies. In addition, humans cannot fly, Terragaians are able to fly.

Ka
Ka is the lifeforce that lives in all Terragaians. Ka cannot be seen, touched, heard, or smelled.
