Fake Irish: Averted. Much of the show was filmed in Ireland, with Irish and British actors comprised all of the main characters.
Keep Circulating the Tapes: A long out-of-print VHS was this series' only home video media release in North America. It has never been released on DVD because of Disney's buyout of the Saban library. It has, however, seen DVD release in Germany, of all places. It can be found online if you look but the only existing copies of the English version are heavily compressed and degraded rips from broadcast recordings that are nigh-unwatchable, making the show a particularly unfortunate version of the trope.
What Could Have Been: The second season would have been called Mystic Knights: Battle Thunder and would have had Maeve finding a sixth Mystic Knight named Seanin, the Mystic Knight of Swamp. His transformation call? Death Below Me.
