Donjo Script (c. 1999)
Originally in 1998 I created a language called Mushroomese, which was the language of a country I called the Frintha. I eventually decided I wanted to have a distantly related language, which I named Donjo. At the time I knew next to nothing about comparative linguistics, so the connection between the two languages was basically random similarities and differences with little thought as to how they were specifically related to each other. Mushroomese script was designed specifically for the limited sound system of Mushroomese and would not work well for Donjo, which had (has) a rather noobish inventory of consonants, so I decided it must have been a recent invention, commissioned by a king or some such and created a completely unrelated script for Donjo.
The script was intended to look somewhat primitive, and was also designed to allow a high amount of interaction between rows of text, obscuring the rows and making it look something like an impenetrable mess of squiggles. This is partly why many of the letters are composed of separate, unattached lines. When I turned the script into a font, naturally this interaction was eliminated and the script became quite linear. The script is featural, with some amount of variation.
Goga (Archic) Script (c. 2000-1)
It wasn't long before I decided I wanted to create the historical parent language of Donjo and Mushroomese. I started working on this language probably in around 2000 or 2001. The language had a noobish phonology similar to Donjo, and the script was closely related to the Donjo script, but designed to be more regular and slightly simpler in appearance.
Marag and Hwagak Scripts (c. 2009)
Some time around 2009 I was inspired to create two more languages and scripts to go with them. I had learned a little bit more about comparative linguistics and had been working on figuring out how Donjo and Mushroomese descended specifically from Proto-Frinthan. I determined that Donjo was one of the northern languages, while Mushroomese was a southern language. I then got to work on designing some central languages. The closely related languages Marag and Hwagak were the initial results.
The two scripts are stylistically quite different, but in terms of letter forms they have many similarities. They were designed almost simultaneously (Hwagak being slightly earlier) and were both intended to have branched off from a descendant of the Goga script. They also function similarly, word boundaries being indicated not by spaces but by special final forms of letters that are written at the ends of words, a feature that occurs only in these two scripts and the closely related Hüskaghurb Script.
*This letter is archaic and not generally used.
As you can see here, I later adapted the script to write Krah, a northern language of the neighbouring region.
*The ascender on these letters is truncated when it appears directly to the right of another letter with an ascender or diacritic.
**The second form is used with letters that have an ascender.
(The vowels of Eastern Hwagak presented here are still slightly in flux; Western Hwagak has more traditional vowels that are more similar to Marag).
One of the things I enjoy about designing scripts in this script family is seeing how much I can obscure or eliminate the featural qualities of the original archaic script.
To come: Roojee Script, Ashusk Script, Hüskaghurb Script, Beeba Script, Gondel Script, maybe Tilid Script someday if I ever get around to refining the designs of it.
'lbby' and 
'nddw'. The script does not indicate or acknowledge word boundaries, so the ligatures will span word boundaries. It is hell creating a font for this...although the letters are usually fairly regularly formed, it's not quite regular enough that I can automate it...I really have to make each character separately.
