Ardenorian

Ardenorian was an early conlang by Jörg Rhiemeier, a daughter of Serindian. The language was meant to be spoken on Ardenor, a planet of Tau Ceti, about 12,000 years later than Serindian. The author did not have any good idea of historical linguistics back then, and the language was unrealistically similar to Serindian, and words were changed haphazardly rather than subjected to regular sound changes. The language was abandoned soon after it was begun.
