The Grand Cosmos.

[Morningstar1337]

The Grand Cosmos was not a part of Voeburt at all but instead Lakeland and the civilization of elves there. Voeburites are drahn and galdjent. Lakeland is elves. The only connection it has to Il Mheg is that a nu mou mage moved in after everyone who lived there died. The shades are probably recreated by them to remember the splendor of the old days before the Flood.

We probably won't learn of any connection of warg gear to the dungeon, if there even is one, until a 3rd encyclopedia comes out.

I see,must had been too hung up on the Ishgard comparisons to overlook the details on the Voeburtites.

Still doesn't explain the choice of name though.

According to the dungeon description on the Lodestone, the palace was so splendid, they named it after the heavens.

Long ago, on the far shore of the Source, a great palace was built by the elves─the Grand Cosmos, an edifice of such magnitude it was said to inspire envy in both the heavens for which it was named and the flowers that pervade its boundless gardens. As with so many wonders of the world that once was, its radiance quickly faded in the wake of the Flood, its halls falling silent, the throne sitting empty. That is, until the palace was given new purpose when a mage claimed it as their sanctuary, their only company being solace, solitude, and the legion of familiars barring entrance to any foolish enough to seek an audience.

So it doeshame something to do with Space. Even only slightly.
