Phanes is a figure in ancient Teyvat mythos who is currently the only proposed identity for the Primordial One. The Primordial One is the progenitor god who allegedly came to Teyvat from another world. It battled against and defeated the seven sovereign dragon-lords who ruled over the old world. After its victory, it went on to create the heavens and earth "for the sake of humanity." According to the scribe of Istaroth who wrote Before Sun and Moon, the Primordial One is Phanes.
