=== Conquerable Ringworlds ===
Up to 8 ringworlds can spawn naturally in a game in various states. Damaged segments can be repaired with the {{iconify|Mega-Engineering|24px}} technology for the same cost as finishing a new segment.
* 1 in the [[Sanctuary]] system. All 4 habitable sections are intact and each contains one pre-FTL civilization, none advanced beyond Steam Age. The system was abandoned by an Enigmatic Observer Fallen Empire but contains automated defense platforms totaling over 50k [[Space_warfare#Combat|fleet power]].
* 1 in the [[Exploration#Cybrex|Cybrex Alpha]] system. It requires completing the Cybrex precursor event chain. The ringworld is completely ruined and requires repairs on each section.
* 1 in the [[Crisis#The Cybrex|Cybrex Beta]] system. It will only be revealed if [[the Contingency]] sterilizes 20% of the galaxy. A short time after the Contingency is defeated, the Cybrex will leave the galaxy, leaving the ringworld free for the taking.
* 1 in a random empty system if the {{iconify|Utopia}} DLC is enabled. It is completely ruined and each section requires repairing. If the {{iconify|Distant Stars}} DLC is enabled as well, the system has a 50% chance to contain a unique anomaly.
* 3 in the systems of the [[Ancient Caretakers]] if the {{iconify|Synthetic Dawn}} DLC is enabled. The ringworld in the home system has 3 intact and one ruined section, while the other two ringworlds are completely ruined and require each section to be repaired separately. If the Contingency appears and the Ancient Caretakers awaken to defend the galaxy, they will also disappear like the Cybrex once the Contingency is defeated, leaving their systems free for the taking.
* Each empire with the {{iconify|Shattered Ring}} origin starts in a ringworld system with an intact segment and two damaged ones. By default only one empire with the origin can be generated, but force-spawning will ignore the limit.
