The Sacred Tree「神樹」 is a magical tree located in the center of the Fairy King's Forest and is the one who gave life to the Fairy Clan. It protects the realm and it's inhabitants through the Fairy King's power.
The Sacred Tree exists in the heart of the Fairy Realm. According to King, the Tree exists to protect the Fairy Realm and has no feeling of evil. Fairies live linked to the Sacred Tree and its magic, and some even are born from it.
The Sacred Tree is the one that chooses the fairy that bears the title of the Fairy King, the one that reigns and protects the entire Fairy Clan. When the Sacred Tree judges necessary to put the next Fairy King on the throne, it gives birth to a new one.
After an unknown amount of time after creating the Fairy Realm and the Fairy Folk, the Sacred Tree thus then selected Gloxinia as the first ever Fairy King and presumably gave him his Sacred Spear Basquias.
After Gloxinia's defection to the Demon Clan as one of the Ten Commandments during the Holy War 3,000 years ago and his eventual defeat and being sealed in the Coffin of Eternal Darkness, the Sacred Tree thus then created Dahlia as the second Fairy King as Gloxinia's replacement. After an unknown amount of time after Dahlia's disappearance, the Sacred Tree thus then gave birth to Harlequin as his replacement, the third Fairy King and current ruler of the Fairy Clan.
The Sacred Tree possesses an enormous magical power. Some fairies are able to access this power and use it, even summon and control its roots and branches in combat. The Tree is extremely resistant, weapons forged from it are more resistant than steel. It seemingly created the Fountain of Youth which grants immortality and was used in place of the Fairy King to sustain the Fairy King's Forest in Brittania.
The Sacred Tree possesses many unique qualities :
- Pollen Garden「
花粒園, Paren Gāden」: The Sacred Tree is capable of emitting healing pollen when it is injured, which also provides protection.
守護獣, Gādian; literally meaning "Guardian Beast"」: The moss that grows in the Sacred Tree is capable of shapeshifting into sentinel beings that fight to protect it from enemies.
光華, Sanfurawā; literally meaning "Light Flower"」: In the Sacred Tree's highest branches grow a flower which can emit powerful rays of solar energy.
- Death Thorn「
死 荊, Desu Sōn」: From the Sunflower is extracted an ivy from which the slightest cut seems to result in death.

Given that the Sacred Tree is also a direct creation of Chaos and being the youngest "sibling" to the Demon King and Supreme Deity and it being creator of the Fairy Realm and Fairy Clan, the Sacred Tree also likely holds godlike power at the same level as its older "siblings".
- King and Elaine are said to have been directly born from the Sacred Tree, unlike the rest of the fairies who were born from flowers and trees in the Fairy Realm.
