Mystic Knights of Tir Na Nog is a fantasy-adventure television series set in a fantasy version of ancient Ireland, created by Saban Entertainment.

A second season entitled Mystic Knights: Battle Thunder was planned, but later cancelled, and its budget put towards Power Rangers Lost Galaxy and the English dub version of Digimon: Digital Monsters.

When king Conchobar of Kells seeks a way to protect his kingdom, protagonist Rohan, a druid's apprentice, goes in search of the prophesied hero "Draganta", with his friend the reformed thief Angus.

Later joined by the foreign Prince Ivar, and Conchobar's daughter, princess Deirdre, they are drawn into Tír Na nÓg, whose king Fin Varra puts the group through various tests to determine their worthiness.

Thereafter the four overcome Mider's "Evil Sentinels" (recurring villains in the series) to capture corresponding suits of armor, and oppose the various monsters created by Maeve, assisted by the winged fairy "Aideen".
