Author here!
I have had these on my Patreon for free, but many have not seen them so I brought 2/3 of them here. This is going to be a collection of short stories on characters that will appear in the book, history of already seen characters and many more. Half will be posted here for all to see, while the other half will be on Patreon for patrons. Check them out if you wish for more :)
