Tilean

Tilean is the language spoken by old Tilea and new Tilea.
Tilea never managed to establish any significant colonies in the New World, but many Tilean immigrants have chosen to immigrate to the New Kislevite and Estalian colonies of the New World.
In the West, most ethnic Tileans speak Riekspiel.  Unless you are a fan of speghetti Westerns, in which case everyone speaks Tilean instead of Riekspiel.
Tilean spoken in the West is near identical to real world Italian with a bit of Western slang mixed in.
