My Astrahus build is underway. This was started by my main character last year but was abandoned when I realised it would tie him down for too long in the one location. I used the Raitaru spreadsheet as a template. The minerals are now covered..
.. and I have started the long process of PI extraction and processing.
It has been a much quicker and easier project to kick off using the resources and knowledge I gained in building the Raitaru.
