Some pics of the 5e reference books I’ve been making for my character and a friend’s.
The Warlock pages use art from an on-line library scan of the Voynich manuscript, an infamous real-life ‘eldritch tome’ of unknown meanings. It’s hard to see in these images, but *every* page has a background image taken from these (if it doesn’t have a larger image used as a space-filler). For most pages, there’s a barely-visible layer of text in an unknown language that is nearly impossible to see.
