Kardii - The alphabet used to write Kardii, the language of the Shela people. It is written from right to left and does not separate words. The imperial lettering style (shown here) closely resembles the Iilkana common alphabet, from which the Kardii one is derived.

Kayalian

Kidarna - Kidarna is intended to appear Sinitic, but is actually an alphabet. Syllables are composed of alphabet glyph blocks, which is inspired by Hangul. Unlike Hangul, the script is not a featural code - meaning that there aren't basic glyphs which are altered to created sounds related by point of articulation. Each consonant has it's own shape. While it appears Sinitic, it has more of a rectangular form to the syllable glyphs, whereas Chinese writing tends to be more square (although, I suppose that could be changed by just altering the width of each syllable glyph when writing it).

Klazurigana - Klazurigana is a rather complex script, which is derived from Japanese Katakana. It has many diacritics used for extending the range of consonant sounds and to make syllable-initial consonant clusters possible

Klingon Print Alphabet - A noncanonical Klingon script for printing, inspired by the official Klingon script (also shown).

Kpuloyi - The writing system of the Mathasian Nidoran Masters.

Ku - Ku is an alphabet for Arkian language. It is a true alphabet, but is built up to resemble characters. It has two basic forms, round and angular, where angular is further divided into rectangular and diagonal.

Kuraw - Kuraw is a script invented for the Saalangal language. I've not really worked on Saalangal, but I have worked on several variations of Kuraw. There are so far a calligraphic variant, a quick handwritten variant, and the typical "book" style, which is what is in the image. This book style is also used for handwriting more formal pieces, but it's not quite as rounded. I've fooled around with other possible styles. It works just like any Indic or South East Asian script derived from an Indic prototype: base consonant plus vowel (/a/), using diacritics to change the vowel of the syllable. It also has final consonants (originally at the ends of sentences, but now at the ends of words ending in consonants), but these are never used alone, except for acronyms. Also, there are a couple of special diacritics. The virama (to use Indic terminology) is a mark that "kills" the inherent vowel. Used primarily in quick notes (when full conjunct characters take a bit longer ! to write), decoration, or for those who are just learning to write, and haven't learned all the conjunct characters. The accent goes either above OR below the glyph, depending what vowel or dipthong diacritic is used (or not used) with the glyph. Kuraw also has a large number of conjunct characters (consonant + consonant vowel groups). The above image shows just a few of them.

Kyorucnek Script - Some weird mix between an abugida and a syllabary. The vowel associated with each consonant depends both of the consonant's rank and diacritics. The Rank I consonants are associated with front vowels, and Rank II with back vowels and isolated consonants. Symbols are also provided for isolated or diphthongized vowels and glottal stop. The script took over 6 months of development but sadly the language it's used to write (kyrorucnek) has never gone further then the step of phonology. I might use it later for another language.
