Berik (Upper Tor) Itik Kwesten Mander [not a distinct language] Dineor (Maremgi) Wares [doesn't exist] Bonerif (Benaraf / Edwas – not the same language) Dabe Jofotek-Bromnya Keijar (Keder) Kwinsu (Ansudu) Betaf (Tena) Vitou (Takar) Foley considers the inclusion of Sause within the Tor family to be questionable due to insufficient lexical evidence.
