Keihan is a constructed language from the Surge Concerto video game series made by GUST. It is fairly complex; what follows are some of my notes on the language.
A lot of information can be found in officially released materials and other pages:
Since there does not exist a detailed description of Keihan's writing system at this time, I have done some research and written one here.
Note that some of this information was derived experimentally and might be inaccurate. Please send me any contradictions you find.
Keihan possesses a straightforward set of alphabet and punctuation characters. Keihan may seem like a substitution of the Latin alphabet on the surface, but that illusion shall disappear shortly.
Here is the alphabet:
There is no distinction between upper or lower case.
Here are the punctuation characters:
Ignore the leading
a characters; they are there to force the official
character generator to render the punctuation.
From left to right, they are
=. The semicolon is Keihan's sentence terminator; it
functions like a period. The reason it is a semicolon may be related to the
strong computer themes in Surge Concerto (this is obvious in the other
language in the series, REON-4213). The equal sign is used as a topic or
subject marker. The question mark and exclamation mark function like they do
Keihan's numeric system is hexadecimal (again showing the computer theme):
While the characters shown above are used for loanwords, they are never used alone in Keihan itself. Instead, they are combined into clusters consisting of two, three, or four characters each.
Clusters come in seven different forms.
Clusters of two characters (2-clusters) have two possible forms.
Clusters of three characters (3-clusters) have three possible forms.
The rules for forming clusters is fairly complex. Using the table below, find the letter in the cluster with the highest priority and use the form indicated by that letter.
These rules were determined experimentally from the official Keihan generator, so they might be incorrect or sub-optimal.
In addition to forming clusters, each letter in Keihan also mutates according to its position in a cluster.
There are nine different mutations.
Here are all of the mutations for all letters:
