Sankhíhten ([sanˈkʰiːʰte̞n], anglicized Sankiten) is the ancient language of a former trade empire that was located in modern Se Nil éce Λúba, Sèè Tjálaa Èkuuholààta, and /TBD\, in northeastern Hkáslyhtá (Kaslota) on the planet Íslíŋŋ (Aysling). Sankhíhten was used throughout the trade empire and beyond as a lingua franca, and eventually came to displace some native local languages. The language continued to be used for centuries after the decline of the trade empire as a language of science and faith, until eventually losing favor to regional languages such as Iathi, Vaseyka, and Oedilaaiffe.
