|Inhabitants|| Dullahan |
|First Appearance||"Back Home"|
Tír na nÓg finds itself in Celtic legends as an otherworldly island existing beyond the western edges of the map. The fairies which inhabit the floating castle are the Titans known as Firbolg and Dullahan.
It was later found by Scarlet Byrne, who was attacked by a rogue Firbolg Titan. Gaining the help of Lok Lambert, who had been having recurring dreams of finding his father at such a place, she enlisted the help of the Huntik Foundation team to return. While exploring the castle, an area of the floor dematerialized, and Lok and Cherit fell into a weak point between dimensions. In this Inter-dimensional World, he was able to speak to his father through a mirror into the Spirit World, Huntik. After returning through the power of Umbra, Lok invoked Pendragon to defeat the Dullahan and Firbolg Titans. Their Amulets secured, Den Fears bonded with one of the Dullahan Titans while Scarlet bonded with a Firbolg.
