All-Mother

The All-Mother is the rarely-acknowledged supreme deity, who created all the gods by her own hand. It is commonly believed that she created the foundations of the world, and then left humanity and the gods to their own devices.

Biography
At an unknown period in time, the All-Mother created the five gods: Alseid, Arethusa, Setine, the Great Angel, and Vega. Both Alseid and Vega imply that each of them were created on separate occasions, rather than all at once. Potentially, there could have been eternities between the "births" of each god.

After the resetting of the world, the All-Mother made one more creation, Genosis. As a cyborg, Genosis recalls being assembled, and it's evident by his body that he was created. All of the five gods are made out of flesh and bone, which may suggest that the All-Mother gave birth to them or otherwise brought them into existence, rather than physically building them.
