The Owl House Wiki

The Emperor's Castle was the home and ruling center of Emperor Belos during his reign over the Boiling Isles, serving as the base of his Coven and followers. It was demolished in the series finale after Belos merged with the Titan's heart in a final attempt to wipe out the Boiling Isles.


50 years prior to the events of the series, the human witch hunter, Philip Wittebane, utilizing the persona of Emperor Belos, took control of the Boiling Isles and ended the "Savage Ages", an era when witches and demons used magic freely. Following his rise to the throne, he founded the Coven System and built his castle as a symbol of unity, directly upon the Titan's chest cavity.

After the events of the Day of Unity in "King's Tide", the castle was deserted by its remaining occupants, leaving it abandoned and its interior slowly suffering from degradation. During the Collector's control of the Isles, the castle was apparently visited by surviving citizens, presumably for refuge, with some having vandalized its interior after Belos's true nature was revealed following the Day of Unity.

In "Watching and Dreaming", after months of being trapped in the Human Realm, Belos, possessing the body of the Bard Coven head, Raine Whispers, returned to his castle in an effort to merge with the Titan's heart in order to complete his plan of destroying the Boiling Isles. Though Raine was able to free themselves from Belos's control, they were unable to prevent him from merging with the heart, allowing him to possess the Titan's body. This resulted in the castle being destroyed in the process, with walls and structures having completely collapsed from the spreading of Belos's flesh throughout the Isles.

At some point following Belos's defeat, a large tree was grown in place of the castle, and ironically, later becoming the location of the University of Wild Magic, as a symbolic testament to the removal of Belos' corruption on the Isles.

Castle Hallways[]

Corridors leading throughout the castle. Despite their main function being to allow easy access to the castle rooms - like most hallways - they have many art features displayed upon its walls, and the walls also have vents. On display at the castle entrance are two tapestries, one depicting the Savage Ages, and the other depicting Belos' introduction of unity and the coven systems.

Further along the hall from the entrance are two statues of Belos, depicting him holding both a glowing orb, and his mechanical staff. Both have their gaze directed towards the entrance to the castle.

Relic Room[]

The Relic Room is Belos' personal treasury, containing magical artifacts that are his own possessions. Each one belongs to one of the main 9 Covens. Despite holding powerful magic, Lilith merely dismissed the relics as "useless". The relics are as follows:

  • Oracle Coven's Oracle Sphere: a purple orb cradled by a 3-headed stone snake. It creates an ethereal version of the user who tells them how to become their best self. According to a pamphlet, the Oracle Sphere was made from the tears of the "Great Eye".
  • Plant Coven's Green Thumb Gauntlet: a wooden gauntlet capable of growing any kind of plant based on the user's imagination.
  • Healing Coven's Healing Hat: a witch hat that can heal any injury and lift any curse.
  • A gold harp from the Bard Coven.
  • A white orb containing purple clay, from the Abomination Coven.
  • A golden vial from the Potions Coven.
  • A silver mirror from the Illusionist Coven.
  • A gold bell from the Beast Keeping Coven.
  • An unknown relic from the Construction Coven.

The room also features statues, presumably of the coven leaders appointed when covens were first brought to the isles by Belos, standing in the rafters, each sporting unique clothing and items. Similar statues can be found lining the room Belos is using to reconstruct the portal to the Human Realm. Only four of the presumed nine statues in the relic room are ever shown to us.

Portal Dome[]

A large dome-shaped room containing Belos' current project, of great relevance to the Day of Unity. Many Emperor's Coven members can be seen working here. The room's main feature is a large, circular ring with white-gold wings splayed at its sides, resembling Belos' staff, being constructed around the reconstructed door to the human realm. In the background, the room also features arches hosting statues similar to those in the relic room.

Throne Room[]

Emperor Belos' throne room. The corridor leading to it and the room itself contains many metallic pipes that serve an unknown purpose. The room itself is lit only by two giant torches from behind the throne. Atop the throne is a gargantuan, pulsing heart, which is revealed to be the heart of the Titan. When Belos is in the room, he is flanked by Coven Scouts for protection.
