For NaNoWriMo 2022, we wrote a cross-over fanfic between the Star Trek Kelvin timeline and the Sunspot Chronicles, and we’ve posted it here, to an Archive of Our Own, if you’d like to read it!
It is not canonical to the Sunspot Chronicles. However, it is a good introduction to our world and stories, and the details about the Sunspot and its people are actually more accurate to the canon than the original stories! Because we decided that the crew of a Federation starship would be more accurate in their reports than a 21st century publishing company receiving mysterious transmissions from outer space might be. First hand accounts v.s. commercialized localizations of translated text, you know.
