Ostrins (Ostric: Òstrskëbi; Navish: Ostrøysker) are the native inhabitants of the island of Ostry.
Language
The majority of Ostrins speak Ostric, a Sclavonic language native to the island. Around seventy percent of Ostry speak Ostric as a first language, with the remaining thirty percent citing Navish as their primary tongue. In both Ostry and the diaspora, bilingualism and even multilingualism is common, and the Navish language, although once forced on Ostrins during the Oppgjørspolitikk, is now increasingly accepted as a part of Ostric culture.
Religion
Ostrins primarily follow the Trúathi faith, introduced to Ostry in the 12th century. On both the island and in the diaspora, Ostrins are generally more religious then their Lhedwinic counterparts, with eighty-one percent members of the church. In countries and regions where Trúathism is not the majority religion, many Ostrins have formed ethno-religious communities, where the main connection between members is the church.
