The concept of the universe seems really exciting, but I do regret that the “primer” says nearly nothing about the world: less than 3 pages to introduce the universe! (compared to 11 pages for combat).
The table of contents is false, there are numerous missing sections, and the page numbers don’t match: the PDF contains only 76 pages, compared to the 95+ listed in the table of contents.
This “primer” is just not usable as is. I hope you’ll correct it, because for now it doesn’t make me want to explore it further. Please don’t make me regret my donation.
