There's two of them and one's larger than the other which leads to assume they are Artaeum's version of Masser and Secunda. Though what world/plane this is remains a mystery.
I think there are more than two moons visible in the sky on Artaeum. On the few occasions when I have taken the time to look there have always been two pairs of moons, set about 180 degrees apart. I don't know if they move.
I went back to see and yes, there is an identical set that seems closer to this bright circle. Whether they orbit or not I guess remains to be seen and if they truly represent Masser and Secunda or that of other Planets/Planes
In the Ritemaster's Study there is this light which I wonder if it is a representation of some kind of orrery
and on a little note, has anyone seen the two Moons in Summerset's sky as yet?
Edit: found these peeking through the clouds in Summerset
and a thought - if these are not the Moons of Nirn in Artaeum then perhaps Artaeum is located in a solar system similar to that of the Dwemer Orrary which showed no Moons.
noticed this the other day as well I was kind of surprised at first to see multiple moons
