“Every myth you humans have is caused by a little of our world linking into yours.”
―Eda explaining the Boiling Isles to Luz
The Boiling Isles is the main setting of the animated series, The Owl House. It is a land populated by all sorts of magical creatures with a town located in the remains of a dead titan. The Demon town is pretty much alive, full of random hands and eyes in strange places.
The locals are very prejudiced towards humans, which forces Luz to hide her identity once she arrives. Located outside the town on a cliff is the Owl House, homed to Eda and her sidekick King.

The design of the Boiling Isles was inspired by various European painters including Remedios Varo, John Bauer and definitely Hieronymus Bosch, who was best known for his surrealistic depictions of hell. Dana Terrace also took a lot of inspiration from Russian architecture as well as medieval church art.
The main reference point for the architecture in the series was from the work of Belgian painter Charles Leickert and the other artistic inspirations were drawn from the work of Dutch painter Hieronymus Bosch, Russian illustrator Ivan Bilibin and Spanish artist Remedios Varo
The design of the woods was originally going to be much more dominated by black colours, but since it was "melting" with Luz's hair too much, the creators went with "bloody red" for the trees.
