I love the new-ish day, night, rain etc system in the game but I keep on looking up at the sky at night and hoping to see the Ring of Siberys and so far I have failed to find it. This is really sort of a flavor thing but I still think it would be cool to see it. Maybe occasionally during the day too. It should be brightest above Xen'drik.
Also to my knowledge I only remember seeing one of the 12 moons. I know I'm being nit picky and I don't figure all 12 moons would be visible in Xen'drik every night but seeing 3 or 4 of them on a regular basis would be cool.
