The son of Ösung was Pälkhortsän (Dpal 'khor brtsan) (865–895 or 893–923). The latter apparently maintained control over much of central Tibet for a time, and sired two sons, Trashi Tsentsän (Bkra shis brtsen brtsan) and Thrikhyiding (Khri khyi lding), also called Kyide Nyigön (Skyid lde nyi ma mgon) in some sources. Thrikhyiding migrated to the western Tibetan region of upper Ngari (Stod Mnga ris) and married a woman of high central Tibetan nobility, with whom he founded a local dynasty.[25]
