So, I've decided to take my existing 7DRL, Stygia (which is a complete game) and use it as a framework to commence an in-parallel (and much less ambitious) rewrite of Kharne, using C# and Libtcod.NET. This one will have a slightly darker, less generic theme (with a magical system based entirely on Goetic magick) and will focus more on atmosphere and personal horror.
No doubt there will be extra-dimensional tentacles involved somewhere.
Don't worry, there will be another release of the existing Kharne (Alpha 24) shortly.
And this mysterious text below? Why the big bad himself, that you will have to defeat. Kudos and a hug to the first person to recognise the language.
