I always find myself looking up in the night sky because the way Secunda and Masser are rendered look absolutely fantastic.

However, I just realized something while watching one of the two moons move across the sky: There aren't any constellations that match those of the star signs from the skill window.

Obviously, this isn't anything major or something that would even be noticed by many players, but one of my favorite things about TES is the lore. In such incredibly detailed game worlds, I can't believe something as simple as putting actual known constellations in the night sky slipped past the art team. For 3 games!

Are you sure they aren't there?

I was looking for it a week ago, I couldn't really find it but I remembered Todd saying something about "looking up" and see the stars light up. Perhaps he was mentioning to the Skill menu.

That is precisely what he meant; I remember that video too. If you notice, when you go into the skills portion of the menus, it is as if your gaze is tilted upwards.
