Nanna
God of the moon and cyclical time. Firstborn of Enlil and Ninlil, father of Inanna and Utu. In Akkadian, Sin (or Su'en).

Etymology
Nanna is an ancient Sumerian name for the moon. Alongside it appears Suen (late Sumerian), which in Akkadian becomes Sin (written Su’en). In the most archaic lists, Nanna and Suen appear as alternative names for the same deity, although some texts treat them as distinct aspects (full moon / crescent moon).
Attributes and Role
Nanna is the personified moon. More than nocturnal light, he is cyclical time: the Mesopotamian month was lunar (29–30 days), astral divination used the moon as its primary reference, and religious calendars revolved around the phases of Nanna. He is also father of Inanna (Venus) and Utu (the Sun) — generator of the most brilliant visible celestial bodies after himself.
Iconographically, he is depicted as a bearded old man in a turban, or simply by a crescent moon upon a pedestal.
Cult Center
Ur — one of the most important city-states of Sumer, at the mouth of the Persian Gulf. The temple of Nanna in Ur, the E-kishnugal, served as the central sanctuary for more than two thousand years. Ur-Nammu (~2100 BCE), founder of the Third Dynasty of Ur, constructed the famous Ziggurat of Ur dedicated to Nanna — still today one of the best-preserved in the world.
A second important center is Harran, in northern Mesopotamia (southern present-day Turkey), where the cult of Sin remained alive until the Roman period, centuries after the fall of Babylon.
The daughter of King Sargon of Akkad, Enheduanna (~2300 BCE) — the first named author in history — served as en (high priestess) of Nanna in Ur. Her hymns to Inanna and to Nanna are the oldest preserved signed literary texts.
Myths
Nanna is not a particularly active figure in the myths, though he is central to the cosmological structure. In certain texts:
- He lends the “me’s of the moon” to Inanna during her journey to the underworld.
- He is consulted by other deities on matters of time, calendar, and divination.
- In Enlil and Ninlil, he is the firstborn who must ascend from the underworld to the heavens.
Syncretisms
- Sin (Akkadian) — developed its own characteristics, especially at Harran: cosmocrat, “highest god,” nearly monotheistic in certain periods. The last Neo-Babylonian dynasty (Nabonidus, 6th century BCE) promoted Sin as supreme deity, in conflict with the clergy of Marduk.
- Yarikh (Canaanite) — also a moon deity, partial parallels.
- Khonsu (Egyptian) — masculine moon, structurally comparable.
- Selene/Luna (Greco-Roman) are not structural equivalents: in Mesopotamia the moon is masculine; in the Hellenic Mediterranean, feminine. This inversion of the moon’s gender is one of the syncretisms that did not translate.
Game Perspective
In Mensageiros do Vento, Nanna appears primarily as temporal structure — ritual calendars, lunar cycles governing encounters, spells, and in-game events. In flashbacks accessible through the Akashic Records, he appears as father of Inanna, a ceremonial and paternally protective figure. His relationship with Enlil (his father) is ambivalent: son of the leader of the faction opposing the Demiurge, yet not his accomplice.
