Destination

Although each of the sixteen heavens is called a heaven, but not all of them are liked by the people of the sixteen heavens.

Dark Heaven is the least populated heaven.

It was because it was the darkest heaven.

It didn't even have daylight, the sky in that place was always dark, and life there was as dark as the light there. Murders, massacres, and other evil things often happen there.

And it is also the gathering place of the criminals in the sixteen heavens.

It was said that the criminals there would protect each other when they faced outsiders.

If they weren't criminals and came there, they would usually be robbed by them. Even Paragons are sometimes killed there.

Of course, that place still had an imperial faction even though their numbers were much less. The Eternal Dark Emperor who became Emperor after Titania was also from there.
