Ylia Cluster

A cluster of planetoids remnants of a planet that has broken apart inhabited by Giff and Thri-Kreen. There are several Spelljammer docks carved into the planets as well as a large Beholder city. It's the closest point to the Wildspace portal leading to the Astral Sea.

 
 

Planetoids

Port Lharea. A bustling port build by the Giff and features many cannons and gun towers to protect the docks. Its build around an ancient wreck of an Astral Juggernaut called the Lharea.
The Hollowed Rock. A broken shard of a planet has been hollowed out and has a system of tunnels connecting to the wooden docks on the outside of the structure. Thri-Kreen inhabit the warrens inside.
Brathl An artificial planetoid made from organic materials with pulsing living tunnels leading to chambers within. Beholders can be seen floating around the structure.
 

Important Locations

Wrecktown. The ancient wreck of the Lharea has been reclaimed and from its bones a town has sprung up. Most of the houses resemble the outside of a Spelljammer with planks, portholes and railings. Most of the inhabitants are the descendants of the Giff crew of the Lharea.
Lharea Docks. Spelljammer docks have been built around the asteroid of Port Lharea. This is main port for the Spelljammers arriving through the Wildspace portal of Hollowspace.
The Hive. Inside the warrens of the Hollowed Rock are the chambers of the Thri-Kreen hive that settled this system. They are skilled craftsmen working tirelessly to create goods, weapons and armor from organic material.
The Mothers Cradle. Inside the Beholder enclave of Brathl is a living city made from strange flesh. It's named after the mysterious Mother that all Beholders worship as a Goddess and the creator of their race. Only a few humanoids dare to live here amongst these monstrous creatures.
