Ulijen (Cordai Gap): Honestly, if I have to tell you it’s a bad idea to visit a planet that looks like someone took a bite out of a giant apple, you probably aren’t able to read this book anyway.
Ulijen is the infamous site of the eponymous Ulijen Disaster, in which an ill-advised attempt to tap power from the system’s primary using a wormhole resulted in the planet being bathed in heart-of-a-star conditions for long enough to vaporize a substantial chunk of its mass: the resulting crater covers a quarter of the planet’s surface area, and the rest of the planet is not a habitable world any more, either.
But that all happened long ago (circa -1,000), you say?
Well, there are three very good reasons not to go that still apply:
One, it’s astonishingly radioactive. Being effectively dunked in a stellar core causes a lot of neutron activation, and while to my knowledge no-one’s actually computed how much shielding you need to visit a planet that glows from orbit 8,000 years later, it’s certainly more than you have.
Two, to call it tectonically unstable would be to call Leytra (Ringstars) ‘bright’. When you vape that much mass off a planet, it tends to collapse back into a proper sphere under its own gravity. This is not an easy, short, or comfortable-to-be-around process.
Three: you want to go there to salvage paleotech, don’t you? Of course you do; that’s why anyone goes to a fossil world. But even if it wasn’t all vaporized in the disaster, you’re then going to try and sell someone a power generation system with a known history of destroying civilizations.
The likely consequences of this are best appreciated by reading my companion book, 1,769 Sophs Who Were Airlocked, And Why They Had It Coming: A Cynic’s Study Of Consequences (Bad Stuff Press, 7920).
