Up in the sky is an always moving fortress: The sky city Altaeria.

The Greco-Roman structure is mostly open to the skies, where heroes fly in. It's a haven, a shelter, a place of research left behind by aerials and created for those who can soar the skies.

It's well-hidden by the positioning of clouds... Or rather false clouds created by steam.

Not only is the view from above stunning, but the skies are open for flying.
