The Celestial Shoal

It depicts a collection of islands that sit at a dimensional nexus.

The Celestial Shoal is a meeting place between many streams into the Alter, and of various layers of the otherealms.
This is a strange and wild place, borne of unique magics and unusual forces.
Many things find their way onto the islands, and at times, on into the waking world.

Travelers, and other beings, slip between worlds, and planes of existence, through locations like this one.

It's a dangerous place, physically and mentally as well.

It touches realms both upper and lower, as well as those inner and outer.

It's best to seek out a skilled and experienced captain who knows the chaotic flows.

Captains versed in the myriad flows can be found at various ports.

Some tend to attract those skilled in a certain destination, so a traveler may need to seek the right port relative to where they hope to go.

But not all captains are to be trusted. So beware travelers.
