The Chthonic Codex is a lot of things. It’s a monster manual (stats compatible with most OSR games). It’s a catalogue of magic items. It’s a chronicle, but not how you would expect it. It’s a non-explicit setting. It’s a book, both fictional and non-fictional. And it’s illustration heavy. How heavy? Look at all the illustrations ready or half-done at the moment.
No, that’s a lie. There are more, but I finished the free space on my bedroom floor.
Nine copies will be hand-bound in dragon skin[*] and available for sale.
[*]: Not real dragon skin, actually salmon skin. It’s soft, grey, scaly and a bit unsettling.

“Salmon-skin covers” interest me strangely. Keep me apprised of your efforts.
I shall endeavour to do that! 🙂
