Altamira, the Seaside Paradise, is a major city in Tethe'alla. It is a seaside resort popular for the Lezareno Company's headquarters, large beach, resort, shopping center, and theme park.

Latheon Gorge is best known for the large number of wind-generating plants that live there. These plants blossom and generate wind when fed Kirima fruit, but wither to a dormant state when fed Amango fruit. Both Kirima and Amango fruit can be found on various trees in the gorge. The gorge itself is very mountainous and tropical. Toward the top, there is a large waterfall that rains down in the middle of the gorge, giving a misty feel to the atmosphere.

Toize Valley Mine is a mining cavern owned by the Lezareno Company. Its primary function was to excavate Exspheres from the earth and power Tethe'alla's technological advancements. It is the primary reason behind the Lezareno Group's rise to economic power. "Inhibitor Ore", which is needed to create Key Crests, is also found in the mine.
