Lingua brahui
Da Ufopedia.
The Brahui (Urdu spelling: بروہی) or Bravi (براوِ) language, spoken by the Brahui, is believed to be a remnant of Dravidian language's mainly spoken in south west Pakistan, although it is also spoken in Afghanistan and Iran. The 2005 edition of Ethnologue reports some 2.2 million speakers, 90% of whom live in Pakistan. In Pakistan it is mainly spoken in the Kalat region of Balochistan.
Brahui belongs to the north subfamily of dravidan family of languages. Although it is a language belonging to the Dravidian language family, it has been influenced by the Iranian languages spoken in the area, especially Balochi.
Brahui is widely suggested to be a remnant of a formerly widespread Dravidian language family that is believed to have been reduced or replaced during the influx of Iranic/Aryan languages upon their arrival to Pakistan. It is also been suggested that Brahui might be a direct legacy of the Indus Valley Civilisation. Conversely, it has also been suggested that Brahuis migrated up to Baluchistan after 1000 CE [1], with one scholar placing it in the 13 or 14th century [2].
