Žskđ (alternatively Anglicized as Zhisketh) is one of my oldest conlang projects that I still use and work on from time to time. I got the idea for a vowel-less conlang while attending the 7th Language Creation Conference in 2017. Using sonorous consonants like n and r to take the place of all vowels in syllables results in a language that sounds quite strange and alien but is still pronounceable.
