Bloodborne: Caryll’s Fate by Istrandar page 227
Caryll’s Fate by Istrandar (Twitter, Instagram) is featured in Soul Arts on page 227.
The artwork contains lots of runes. The formless oedon rune is featured in the endpaper. Many of the other ones are references to Bloodborne and some are new creations. One rune in the endpaper looks like a modification of the Heir rune with a split center line. Maybe a reference to Bloodborne II (which was the theme of the art competition)?
