My study area lies on Tekuo, an Earth-like planet inhabited by sentient hominids. Tekuo is one of seven planets orbiting a class G2 sun, known as Ayu. The first four planets in the system are rocky. Tekuo is the third of these. Three gas giants lie in the outer part of the system. Tekuo is the only planet in the system to lie in the habitable zone.
The island of Mohai lies to the east of the continent of Aheku on the planet Tekuo. It lies in the tropical zone and has a monsoon climate. It has an area of 162,350 square kilometres (62,683 square miles) and a population of 13.2 million. This works out at 81.8 people per square kilometre.
