Seth is the second planet available to players. It is known for having large quantities of gold. It has an Egyptian theme. It is also mainly based off of what appears to be a barren desert with many desert themed enemies.
It is most likely that Seth is named after the Egyptian god of the desert and chaos, Seth(pronounced Sett, sometimes known as Sutekh). Seth was the brother of Osiris and is recognizable by his head, that of an unknown animal, believed to be based on an anteater.
