Constellations and the Night Sky

[Enkidoh]

The moon (not Dalamud, and on that note, does the regular moon have a name too?)

Isn't the primary moon known as 'Menphina' after the goddess of the moon and love Menphina?

Dalamud after all was referred to as 'Menphina's loyal hound', so that alone seems pretty concrete that Eorzeans call the primary moon and the goddess of the moon by the same name (after all, in real life the word referring to Earth's moon ('lunar') is derived from the Roman goddess of the moon Luna, so there is definitely precedent there.).

I did notice that the little corner icon for phases is backwards for waxing/waning according to the northern hemisphere convention I would expect Japanese programmers to use, so either Eorzea/Aldenard/Vylbrand are in the southern hemisphere of Hydælyn or the moons orbit backwards relative to the planet's spin (which is set, since we know the sun rises in the east and sets in the west just like Earth). A retrograde orbit is a huge red flag in terms of plausibility especially given a larger sized moon, but not necessarily impossible. Either that or it's developer oversight. :P

Well, it appears to me at least that Eorzea is in Hydaelyn's northern hemisphere - at the end of at least two of the ARR trailers where it pans out to show Hydaelyn from space it seems to show Aldenard and Vlybrand in the northern hemisphere of the planet. But it's not very clear after all (if I can find a screencap of the trailer in question I'll post it here).

EDIT:



It's not the best (I had to increase the brightness to show the planet's detail), but I managed to pull a screenshot from this trailer, and you can see Aldenard and Vlybrand quite clearly - although the sun is obscured behind Hydaelyn the light bloom on the top right corner of the planet hints at it's axial tilt, thus showing that Eorzea is pretty conclusively located in the northern hemisphere.
