Daesi
Daesi is the fourth and last junction world of Meon Cluster. It was the last one to be discovered as it merges with Kooine and Tydus, but not Sfal.
Daesi was predicted by calculations many cycles before it was actually discovered. Nevertheless, the first few teams sent to explore it perished. After a few tries, a Tarvissian sorcerer, Vespar Garrathur, managed to return with the information that the entire world was filled with water, with no surface and no bottom. If it were a normal world, Dahlsi would consider it uninhabitable and end it there, but as a junction world, it promised a way to an untold number of other worlds. Therefore, Dahlsi sent the emissary to contact a half-legendary species, the hrefn, to help them colonize it.
You can read about the expedition in my novella Octopus Song.
With the help of hrefn, Dahlsi were able to establish two cities, Marka-Na-Daesi and Danart. They were connected by a web of tunnels that also stretched out to a handful of actually settled worlds. Many more were explored, but the difficulty reaching them deterred most of the potential inhabitants. Meanwhile, hrefn built their own city and started hunting local fauna for blubber, pigments, and drugs, even agreeing to pay tribute to Dahlsi. Most life forms in Daesi are invertebrates, some looking like giant worms or cephalopods, others resembling exposed viscera. Luckily, the eternal darkness shields them from view most of the time. Near the edges of the world, where the sky-bubble lets in a bit of Vhalfr-light, colorful zoophytes evolved to produce intense pigments they use for mating displays. Those pigments are one of the most valuable resources of Daesi. That is, after biava: a slime of certain sea-slugs that affects humans in a way similar to alcohol.
