Glisque

Glisque is the liturgical language of the Anglian Church of Britany, it evolved from late Old English and it was replaced by the predecessor of the modern language of Britany, Anglé, an Anglo-Norman based romance language.

Dialects
as a living language, Glisque only managed to remain widely spoken in North East England for a period of time, thanks to that it was only sub-divided into 3 mutually intelligible dialects, Rulian, the most widely spoken one which forms the bases for the modern liturgical language, Scherian, the second most widely spoken dialect, and Mavalian, which was only spoken by around 10% of all anglophones in Britain at the time, many small communities still spoke other germanic dialects but those showed significant deviation from the main dialects and they died quickly compared to Rulian.
