The Ring of Siberys

Despite its proximity to Eberron, the unstable and dangerous nature of the Ring of Siberys has not been extensively colonized. Settlements are located in larger fragments, and are mostly concerned with their own self-sufficiency. Though anomalies can be found throughout Siberspace, and the Astral Sea beyond, the Ring of Siberys has the highest concentration of strange, unusual, or arcane structures. These include a variety of ruins left behind by dragons, giants, native celestials, and explorers from Ohr Kaluun. Just like Khyber's demiplanes, there are many alternate realities in Siberys, contained within the hollow asteroids. It is common that entering an anomalous feature will result in exploring a realm that is bigger than it is on the inside.

Sample dragon ruin: The Three Rings of Vogarac This ruin consists of three enormous golden rings linked together, already a fortune beyond anyone's dreams, if they could be disassembled. However, the true treasure is inside: stacks upon stacks of research into the Daughter of Khyber and the corruption she represents. The rings were crafted by a brass dragon called Vogarac and his followers, who believed they needed to remove their research away from Eberron entirely to be sure their words were not altered or corrupted by the Daughter or her servants. The dragons who lived there are long gone; now there remains a population of lizardfolk and dragonborn scholars, who are friendly but will ferociously attack anyone who tries to remove any scrolls or tablets. Hearing of lizardfolk on Eberron, they will deny it vociferously, believing themselves to be the only ones.

Sample Giant ruin: Khomad Moraz During the height of the conflicts with Dal Quor, a terrible weapon was unleashed which shattered Xen'drik and destroyed Crya, the thirteenth moon. The massive tower of steel and rock was the Cul'sir's desperate attempt to end the war. It was supposed to break the manifest zone on Crya, using power drawn from Khyber, Eberron, and Syberis, and while successful and breaking the link between Dal Quor and the Material Plane, the unpredictable energy caused Xen'Drik's downfall. This was the conduit that channeled Siberys' Blood to destroy Crya; it is chock full of Siberys shards, but all of them are burnt out and used. It was built and manned by ancient warforged, who remained on the tower. Their long isolation has made them hostile and hungry, and any metal or scrap intruders bring are aggressively foraged.

Sample Demiplane: The Revelrous Demesne Hidden inside a large, discoid asteroid is a lush, gorgeous landscape, full of rich fruit, flowing rivers, and quaint villages populated by satyrs, overflowing with good nature. The danger is not immediately apparent; in this demiplane, all water is replaced with alcohol. The fruits are like deceptively sweet cocktails, the rivers taste like wine. Even the water vapor in the air imperceptibly makes those who are capable of being drunk more and more intoxicated. The satyrs are accustomed to the unique nature of the demiplane; however, visitors become more and more impaired, and must cope with decreasing faculties to find the way out before they begin dying of alcohol poisoning.
