The idea is simple!
I was in the middle of a paleolithic-to-ultratech playthrough, when I had a fun idea that I could use a gravship in the medieval era to start up something of a pirate crew instead of a traditional kingdom, but then I realized that Mr. Potocki didn't add a way to farm astrofuel pre-electricity, so the ship wouldn't be able to run.
I obviously didn't take that sitting down; I want a gravship pirate crew, and there's no grav anchor nor biofuel refinery that can gatekeep it from me!
Because of the above dilemma, I took the obvious answer and decided to add astrolopes, a newcomer to gravtech-influenced rimworlds that produce astrofuel instead of chemfuel.
Astrolopes can be obtained from exotic goods traders and slavers, allowing you to purchase them at any point you get the oppertunity.
You can also find them at a new tile mutator if you're using Vanilla Landmarks Expanded.
