Tchekor is a Fulgora & Vulcanus replacement to be used as part of the Solar System++ and Journey projects. It uniquely blends mechanics from both planet production mechanisms together on a tight space.
I plan on adding that as an option this weekend. (I'll be moving the logic for replacing planets to a mod pack and all the planets can be installed individually once that occurs). At this moment we're running this planet as part of a playtest on Comfy Playtest Hexalith server (along with a few others), to see what values need to be changed.
