Abwaxa (also known as Magha) is one of three main islands of the Daihexi archipelago. Among them, it is the southernmost one. It is characterized by an extremely wet climate with high temperature variations from the summer to the winter.
It was the last of the Daihexi main islands to be colonized by humans around 3000 BEA. They came from the islands in the southeast, Sho and Ahi. Due to those islands' colonization by the Arcesian People and then their history with the Sâtoun people, their original inhabitants mostly mixed with the new population and didn't survive as a group. Due to their link with the inhabitants of Magha, they share the name of the Maghan people.
