The Sand Goddess, and Spirit Temple interiors have mock Egyptian hieroglyphs on the walls. The Greco-Roman architecture built on top of the older Egyptian architecture, in the Arbiter's Ground, make me think of the Hellenization of ancient Egypt. It may be telling the player what kind of symbols to look out for ie Hellenized Egyptian. I think the moon tears are a Hellenized Isis reference.

This is the dark Link cut-scene from Twilight Princess. It's creepy as fuck, and full of light/dark symbolism.

Considered the master shaper of the world, god of wisdom and of all magic, Enki was characterized as the lord of the Abzu (Apsu in Akkadian), the freshwater sea or groundwater located within the earth. In the later Babylonian epic Enûma Eliš, Abzu, the "begetter of the gods", is inert and sleepy but finds his peace disturbed by the younger gods, so sets out to destroy them. His grandson Enki, chosen to represent the younger gods, puts a spell on Abzu "casting him into a deep sleep", thereby confining him deep underground. Enki subsequently sets up his home "in the depths of the Abzu." Enki thus takes on all of the functions of the Abzu, including his fertilising powers as lord of the waters and lord of semen.[14]
