The Mystic Knights of Tir Na Nog - Plot

Plot

Queen Maeve of Temra wants to rule the land of her birth, the peaceful kingdom of Kells. She therefore calls upon the dark fairy Mider, who gives her the mystical Rune Stone that allows Maeve to use sorcery, most often to summon mystical, dangerous creatures like ogres and evil giants, whom she sends to destroy Kells. King Conchobar of Kells hears of Maeve's evil plan and seeks a way to protect his kingdom and peoples. Rohan, a druid's apprentice discovers an ancient scroll telling of a legendary warrior called Draganta who would save that kingdom. Because Rohan's birthmark matched a prominent sign on the scroll, the King sends Rohan on the quest to find Draganta, with his friend the reformed thief Angus.

The two are joined by the foreign Prince Ivar, and the king's daughter, Princess Deirdre, follows them. They are drawn to the realm of Tir Na Nóg, ruled by the fairy King, Fin Varra. Fin Varra puts the group through various tests to determine their worthiness, which they pass. King Fin Varra gives them another section of the ancient scroll, and mystical weapons which give control of the Classical Elements Fire, Air, Earth, and Water. The four young warriors battle the four Sentinels of Temra, who guard elemental armor, and defeat them, earning the title Mystic Knights (Rohan becomes the Mystic Knight of Fire, Angus Earth, Ivar Water, and Deirdre Air).

Each Knight can call upon their mystical element for powers unique to it. Aideen, a small, winged fairy, continues to offer periodic assistance to the young heroes as they battle Queen Maeve. Eventually, Rohan manages to tame Pyre, the Dragon of Dare. This feat, and Pyre's later assistance as an oracle, reveals Rohan as the legendary hero Draganta. Later in the series, another Mystic Knight emerges; Garrett, the Mystic Knight of Forest. He begins as an adversary under the control of Queen Maeve, but frees himself from her influence, throwing his lot in with the Mystic Knights. Garrett and Rohan develop a rivalry for Princess Deirdre's affections.

Eventually Queen Maeve summons a new monster named Lugad who is more powerful than any previous creation. Lugad is revealed to have a birthmark similar to Rohan's, which is explained when it is revealed that Rohan and Lugad are in fact half-brothers, whose mother is Queen Maeve. In the series finale, they eventually work together with the other Mystic Knights to defeat Maeve, who ends up banished by Rohan, her own son.
