The Void

The Void is a dimension that's existed since the first spirits came into existence, created as a result of magic use. It can only be accessed using very specific spells or from dimensional rips, so is considered to be nothing more than a rumor by most spirits. The Void Club was named after it meaning that, indirectly, so was Skyvoid City itself.

Location
The Void is an infinitely massive, space-like dimension. It appears to contain stars however these are revealed to only be the distant remains of flare magic. There is breathable oxygen there, but there is no gravity whatsoever meaning you are always floating. Because of it's link to the real world, everywhere in the void has a real world equivalent. For example, if you were to summon an entrance to the void in Skyvoid City, fly down whilst in the void and summon an opening there you could end up on Earth. Most who go there never return, so tattered belongings floating around are common.

When there, time still passes but you don't get hungry or thirsty. However, once you leave you'll feel the effects of them unless you stayed nourished once there. This is why many that get lost there die instantly after being rescued.
