Aw, I thought I could just leave it a mystery
I originally created, using Vulgar, a language called O'dán, for use with the Lord Ch'sebur'gah Discord bot. But since then, Vulgar received larger updates and couldn't read my exported settings anymore. It's possible to use an older version instead, but I wanted to see what the new version had to offer. (If anyone's interested, it was mostly a system for affixes.) Sadly, some previous settings were also removed and are now just random again. I hope they fix that and add even more custom settings. Anyway, Irdruian is partially based on the settings used for O'dán, but due to randomness distinctly different. E.g., the grammar is much simpler.
The primary goal of both languages was to use many different vowels with a dark u-like sound. O'dán was a bit closer to what I intended, but Irdruian is neat in its own way. I wanted to create a language that would be used by the old ones (Lord Ch'sebur'gah in particular), originally inspired by ... whatever the "Cthulhu fhtagn" language is, but as you can see, the result looks quite different.
After
@Varik Keldun's poetry thread I felt inspired to use the language for poetry. Turns out that writing poems in a language you don't speak just from a very basic list of grammar rules and a short list of words is... something else. I couldn't even try to think of rhymes because I was preoccupied with trying to figure out word order and grammar; all the present near-rhymes are accidental.
