Dalriada was a kingdom in Scotland during the Dark Ages.
Real World Background
As in Shari's story, Dalriada was founded by Irish immigrants under Fergus around 500; it was named after their original homeland in northern Ireland. Its Scottish inhabitants gradually grew more powerful, until in 843, their ruler, Kenneth mac Alpin, became the first High King of Scotland, supplanting the Pictish chieftains.
