Omlandish is the principal language of the Hudresh of Omland. It derives mainly from the dialect spoken by Feidresh living on East Island, where Hudresh traders and fishing folk had lived for centuries in close association with the Feidresh, adopting their language and many of their customs.

When Om, the son of Ishmod, first established trading posts along the northeast coast of the mainland, the inland regions were inhabited mainly by Gobdresh, Tordresh, and scattered settlements of Feidresh. The trading posts attracted many setters from East Island, particularly after the discovery of rich copper mines along the coast of North Omland. The influx of East Islanders resulted in a population that to this day mainly speaks a tongue originating in East Island, rather than the imperial tongue, Gyrish.
