Tilennan

Tilennan is a Indigenous North Avalonian language spoken by around 42 million people as a first language and about 12 million speak it as a second language. The language is almost solely spoken in the Federal Empire of Tilenno, where it has official status. It is the third most spoken native Avalonian language after and. Outside of Tilenno, Tilennan is spoken as a minority language in multiple large cities around the world, mainly caused by the great Tilennan diaspora of the 60s.

Tilennan doesn't have any relative languages left. This can mainly be attributed to the standardisation of the Tilennan dialects and the loss of many other native North Avalonian languages during the colonial time. However Tilennan has a sister language in the Doorasan creole spoken in around the lake of Kuuster. The languages of the North Tethys Ocean are also believed to be a decendent of Tilennan, supposedly a evolving from the Old Lamosan languages.
