Oh sure
How you would get to the skypia dimension? Well I guess one way would be to build an air ship that takes you there.
The skypia dimension itself is much like the aether, but with skypians as the local villagers. In between large collections of sky islands are vast stretches of air. I don’t know what kind of life exists in skypia but I assume that birds have most of the roles such as herbivore, apex predator, and so on.
