Did you ever write a lore document or primer for your charcter's various settings and timelines?
Yes, and no. My lore documents for Thaminga and Kaz's setting are... kinda laid bare right here - a big collection of text files and images that I've whipped up over the years, some more relevant now than others; as much as I probably should publish it all in a more legible format for others sometime, I haven't really found the time or need to (don't have many people asking about it, usually!) - the working title, 196,000 Elshaweþyj is just Standard Isarthakan for 140,000 Lightyears1; synonymous with the scope of the setting, being the Milky Way and its direct surroundings.
Vera's setting meanwhile... honestly the closest thing I even have for a lore document there is some writings on a personal Discord server that I think I copied into its own text file at some point, but otherwise mostly exists on, in all places, her goddamn F-list profile. Definitely need to... actually collate that elsewhere too. All in due time, I suppose. <3
1. Unit systems notwithstanding, of course - Isarthaka's years are shorter given it's a planet orbiting a slightly less massive star in a slightly closer orbit, ergo, so is the lightyear!
