Looking for Uncharted systems concepts

[Valdorel]

1: Ruined megalithic structure.

A system composed of the system-wide wreckage of a Daam K'vosh superstructure, something akin to the dyson sphere (though maybe not quite that big) but obviously destroyed in some long forgotten cataclysm. Something that pre-dates their creation of the Nomads so that the Nomads would be just as surprised about it's existence as humanity is. System could include rare minable commodities such as special artifacts/azurite/wreckage that would be coveted by nearly any research station in Sirius. As well as interesting RP potential for researching Daam K'vosh engineering.

2: Hazardous 'Gold' Rush

System surrounds an dying and chaotic star at the end of its life that has begun to shed its outer layers as many mid-mass stars do near death. This shrouds the system in a gas cloud that is volatile and riddled with explosive pockets, but also hides an asteroid belt rich with extremely valuable minable resources. If possible it could be fun if the system included more invisible hazards such as randomly placed high radiation zones forcing players to manually chart out the safe paths through the system to reach whatever ores or commodities the system holds. Anything that would make a system difficult to navigate would fit perfectly here.

3: Cracked Moon / Prototype Drive

System contains the wreck of a vessel resembling a modified version of the old LCC Explorer vessels that charted space using the "Liberty Engine" in the era before Jumpgates. The wreck is positioned in orbit above a Gas giant with a moon that's been broken apart. What little is recoverable of the logs indicates that A: They were testing something called an "artifact engine" that was expected to invalidate the Valhalla Research Jumpgate Project. And B: The results were disastrous, the vessel was left dead in space as the engine compartment of the ship has either been destroyed or deposited elsewhere in the system. And it seems their post-jump reentry directly caused the destruction of the moon they are sitting above. The system should ideally include a Dark Matter Nebula similar to Kepler/Galileo, which fits nicely with the lore considering how many jump-related projects have been ended due to similar anomalies. Might be interesting place a temporary Scidata location near the vessel/moon rather than a simple commodity.
