We have added a Random Subsector Generator that uses Cepheus Engine rules. There is also a Subsector Editor. Check it out!
The Random Subsector Generator has lots of options to choose from, so that you can generate subsectors that matches your own setting. If you still want to change something, then you can use the Subsector Editor.
