Atium

Atium was the original god that governed over the Void before the Cosmos were created.

History
Atium has always existed and always will exist. He was the original god before the others were formed. Before he created the Cosmos and Arteah, Atium ruled over the Void, which is simply the realm consisting of the absense of all Elements. There was nothing but him. He created the Cosmos to accompany him, and with it, Arteah to rule over. However, the Void continued to exist, outside the realm of the Cosmos. Atium resolved he would not be able to rule over both and split himself in two, resulting in the birth of Xandros at the formation of Arteah.

Duties
Atium is the god of the Cosmos and the original deity of Arteah. Thus, he is the most worshipped god on the planet, particularly by Ivor humans. The other gods are created by him or split versions of him, so, in many ways, Atium is in charge of all their duties. These duties include ruling over all the Elements and the ideas associated with them (nature, industry, war, and peace).
