Illyrian - A South Slavic language spoken in the Federation of Illyria. Being part of a dialect continuum, in which includes neighboring Serbian and Bulgarian languages, its standard dialect is based in Ikavian Shtokavian subdialect spoken in the capital Tuzla, its surrounding metropolitan area and Bosnian regions.
Sorbian - The standardized variant of the Sorbian language branch of the West Slavic language family, spoken in the capital Cottbus and surrounding area. Originally a pidgin/koiné (depending on the linguist's point of view), it became the de facto mother tongue of the Lusatian capital in the 19th century as immigrants from both Lower and Upper Lusatia came to the city and raised mixed-language families, expanded after both World Wars with the creation of the Cottbus metropolitan area.
Kristang - A Mozarabic-based creole spoken in Cotabato and its surrounding metropolitan area, the capital of Bangsamoro. Containing elements from Malay and surrounding languages of the area, it was originally spoken by Moroccan merchants who intermarried with local women, some of them were members of the local nobility, it became the mother tongue of the city and the surrounding villages in the following centuries as more intermarriage (both Morrocan and Spanish Levantine traders and settlers) and immigration changed its demographic landscape; even the traditionally Ebionite nobility began speaking it. The term "Kristang" originally described the Moroccan traders, who practiced Mozarabic Christianity (a mix of Roman Catholicism with some Ebionite elements), although there are now three main religions in contemporary Bangsamoro: Ebionitism, Mozarabic Christianity and Roman Catholicism.
