Koblin language

The Koblin language was a language historically spoken by the Goblins who used to live in Artaburro before getting exterminated after 270 AEKE. What remained of the surviving speakers were expelled into inhospitable territories. If the descendants of the survivors still linger on, the number of speakers of this language may be in a few hundreds instead of zero - nevertheless, for all practical purposes, the language is considered extinct.
