The Fairy King's Forest, later relocated and renamed as the New Fairy King's Forest after the destruction of the original, is a forest within the Fairy Realm and the Human Realm. It marks the border between both realms. Before it was completely burned down due a Red Demon's purgatory flame, the blame of which was placed on Ban, the fairy nation was an ally of the Kingdom of Liones.[1]

The Fairy King's forest (and by extension, the entire Fairy Realm) is ruled by the Fairy King, who is chosen by the Sacred Tree.


The Fairy King's Forest is home to the Sacred Tree of the Fairy Realm which lies in the center of the forest, the fairies all live in the sacred tree which acts like a portal between the human realm and the fairy realm. It is surrounded by a barrier that can be manipulated in order to keep out certain individuals.[2]

700 years before the series started, the Fairy King Harlequin, who had ruled the forest until then, abandoned the kingdom[3] to rescue some captured fairies which included his best friend Helbram, forcing his sister to protect their country's greatest treasure, the Fountain of Youth, in his place.[4] According to Elaine, many people sought out the Fountain of Youth and attempted to attack the fairies' country but all were thwarted by Harlequin.

Originally situated at the northern tip of Britannia, the forest was eventually relocated to the west of the Forest of White Dreams.

Ban tried to fight the demon by ripping one of its hearts out but Elaine explained that demons have more than one heart. She was then clawed through by the demon, and so was Ban, and this gave both of them a fatal wound. Elaine gave the fountain to Ban so he could live but he refused and Elaine made him drink it mouth to mouth and it gave him his immortality, which allowed him to kill the demon, but the forest was still burnt down and he was blamed for its destruction.
