I'm proud to announce that my first requested language is finished.
Dryym's Demonic language has been fully constructed, save for being populated with words. I encourage you to check it out in the 2nd post on this topic.
The entire project took a total of around 150 hours at most, over the course of about 2 months. I've had other things going on in my life, so this wasn't a priority.
Once again, if the topic becomes more popular, I will be more than willing to devote more time to creating more languages.
