A highly exclusive language used by people on Bysonce Island, Planet Ashr in my video game Endless Sea of Stars. This one is used for private documents and old government records, and its brother language Eudastiphos Hand is used for public court documents.
Calystiphos Hand is much simpler than its brother language, despite looking much more complicated. Each glyph refers to highly specific concepts and so it is most used to record time-tested, factual information rather than stories or fiction. However, these glyphs can still be considered as runes, as each one is host to whole mysteriums of information and idiomatic knowledge which have been associated with it.
Bysoncians use a base-8 system of numeracy. 9 would thus be written as 81, 10 as 82, etc. There is no numeral 9.
Calystiphos is the Ashrian god of siroccos. The simplest way to put it is to say that he represents the "yin" of the pantheon.
