Demon Lord's Castle
The Demon Lord's Castle is the residence of the Devildom's ruling family, though at the time of MC's arrival, the only royal family member living there was Diavolo. It was described by Satan in Lesson 6-19 (OM) as "the most magnificent, impressive structure in all of the Devildom."
Overview[edit]
As mentioned by Barbatos in the chat A Shortage of Helping Hands, the Demon Lord's Castle is a popular tourist attraction. Guests are able to make reservations and have hired tour guides take them through the castle. Diavolo also mentioned in the Devilgram Demon Lord's Castle Tour that "there are many places inside the castle for guests to enjoy."
According to Mammon in Lesson 6-19 (OM), there are many rumors about the castle. One such rumor is that Barbatos has a secret torture room beneath the castle, and that every night the screams of his victims can be heard.
Another rumor is that behind a huge mirror is a hidden entrance to a secret, underground labyrinth that houses "a monster that feasts on the innards of demons." MC learned in Lesson 7-14 (OM) that at least parts of this rumor are actually true.
History[edit]
In the Devilgram Demon Lord's Castle Tour, it is implied that either the current Demon Lord's castle has only existed for two generations, or it was completely renovated from a previous iteration by a legendary architect hired by the demon king before Diavolo's father.
As stated by Little D. No. 2 in Lesson 7-10 (OM), "the history of the Demon Lord's Castle is the history of the Devildom itself." The castle is filled with historical artifacts and valuable items. As seen in the Pop Quiz Absolute Zero, one of these items is a strand of fur from the white wolf of frost flowers.
There are also many portraits and works of art throughout the castle. In one hallway hangs a magical portrait of Helene, and the witch herself is trapped within it. After the first incident involving MC finding themselves in the underground labyrinth — due to being sucked into Helene's magical portrait — Diavolo warned everyone in Lesson 7-20 (OM) to be careful while staying in the castle, due to there being "a number of items here with suspicious histories."
Architecture[edit]
The castle's architecture may be Neo-Baroque, as the staircase in the castle looks to be inspired by the grand staircase in Palais Garnier.
Diavolo stated in the Devilgram Demon Lord's Castle Tour that the architect who designed the castle is considered legendary, but no one knows his true name. Supposedly, the demon king before Diavolo's father "happened upon a small house that was designed by the architect," and he was so impressed that he tracked down the architect to design the Demon Lord's Castle. It is implied by Diavolo's demeanor that something unfortunate happened to the architect, but he did not expand on the details.
Diavolo mentioned in the same Devilgram that all of the pillars in the castle are designed so that their circumference "gradually becomes smaller as [they get] taller." In the Fab Snap video Castle Secrets, he also said that the castle "has many secret passages."
Rooms[edit]
Common Areas[edit]
Ballroom/Great Hall[edit]
The castle is known to have a large area used for dancing, as in Lesson 8-8 (OM), there was a dance held after dinner with "guests from across the Devildom," and a large number of them according to Simeon. It's possible this dancing room is located beyond the pair of curved staircases in the Grand Foyer, as the Majolish Wallpaper Nightmare Dance depicts ghostly dancers in this room.
Breezeway[edit]
The castle's Breezeway was first mentioned in Lesson 25-8 Hard (NB).
Collections Room[edit]
This room was first mentioned in the Devilgram Angel vs. Demonic Butler. It contains rare magical items and works of art, some of which Barbatos stated are known to "come and go of their own volition." He also mentioned that not all the objects kept in this room are safe to interact with.
East Hall[edit]

Library[edit]
Satan mentioned in the chat Slumber Exchange (Castle Edition) 16 that this library holds "rare books from all three worlds."
Barbatos told Satan in the Wanderers' Whereabouts video call The Memory of a Brilliant Butler that all the books in the Demon Lord's Castle have a mark on the inside of the spine that only he knows about. However, when MC questioned if this was actually true, he simply replied "Well now, who can say?"
Grand Foyer[edit]
The castle's grand foyer was first seen in Lesson 7-2 (OM). Unlike the majority of the castle's rooms and their darker color schemes, the foyer has very bright tones. The champagne pink floor is likely marble, and has a design of decorative, concentric circles outlined in a copper color in the center of the room. Diavolo stated in the Devilgram Demon Lord's Castle Tour that "it's said this design in a magic circle that was drawn to protect the Demon Lord's Castle." Within the circles are "ancient runes used by demons long, long ago."
There are two sets of curving stairs leading up to an indoor balcony on the second floor. The room's walls are pink-tinged terra cotta colored, as are the pillars holding up the high ceiling. At the point where some of the pillars meet the vaulted ceiling, there are a few decorative skulls.
There are several portraits on the walls, which are presumably of members of the Devildom's royal family. One of the portraits in this room is of the Demon King, as mentioned in Lesson 7-10 (OM). Either sitting beside the portrait or painted in the portrait itself is a crown that belonged to the previous Demon King, whose inscription is etched into the crown's inside surface. Beyond the stairways, large windows with vivid red curtains can be seen on both the first and second floors.
The foyer is filled with the color gold. Gold decorates the base of the pillars, the upper walls have elaborate gold patterns, portraits have gold frames, and the room's lighting comes from sconces and a chandelier all made of gold.
There is an enchanted vase displayed in this room that transports anyone who touches it to a random location within the castle, as seen in the Devilgram Demon Lord's Castle Tour.
Bedrooms and Private Rooms[edit]
Barbatos's Room[edit]
Barbatos's room was first seen in Lesson 15-17 (OM).
Diavolo's Room[edit]
Diavolo's room was first seen in the Devilgram Enchanted Pudding.
Dungeon[edit]
In Lesson 9-8 (NB), Barbatos mentioned that the castle has a dungeon located at the far end of the castle's west wing.
Guest Rooms[edit]
First seen in Lesson 6-17 (OM).
Storehouse[edit]
This storehouse was first mentioned in the Devilgram Ready for a Real Show!. As Barbatos explained in the Pop Quiz Tears in the Devildom, there are many magic - but potentially hazardous - items kept here.
Vault[edit]
Lucifer mentioned in Lesson 7-20 (OM) that Mammon once attempted to sneak inside this vault. In Lesson 8-A (OM), Satan spoke of a rumor he'd heard that "a powerful curse has been put on the room that houses the castle's treasure." Supposedly, if "someone with a heart full of greed" seeks out the vault, a "ferocious demonic beast" will appear and chase them away.
Stairways and Labyrinth[edit]
Labyrinth[edit]
The castle's underground labyrinth was first seen in Lesson 7-14 (OM). According to Diavolo in the Devilgram Demon Lord's Castle Tour, no one knows how extensive the labyrinth is, or where it leads.
Stairways[edit]
This room with multiple stairways was first seen in Lesson 7-10 (OM), and could be inspired by the grand staircase in Palais Garnier. In the Devilgram Demon Lord's Castle Tour, Diavolo explained that this area was designed by "a very famous architect from centuries ago" who is "well-known for utilizing symmetry in most of his work." Diavolo also said the sculptures engraved in the banisters were made by a famous sculptor.
This room is also filled with paintings, including one of the Celestial Realm, as pointed out by Luke in Lesson 7-10 (OM). Diavolo mentioned that it was painted around the time that he first met Lucifer. Another painting in the room is by an unknown artist, which Diavolo points out in the Devilgram Demon Lord's Castle Tour. It's thought this painting is cursed, because "many demons have lost their minds after being faced with its beauty."
Grounds[edit]
Courtyard[edit]
The castle's courtyard was first seen in Lesson 8-19 (OM). In Lesson 3-4 (NB), Satan mentioned reading a book about the Demon Lord's Castle that said when the Devildom was still young, there were many stars raining out of the sky. There was also a giant pit known as "the Starfall," which was eventually used as part of the gardens of the Demon Lord's Castle. This pit became the lake that sits next to the castle courtyard, which Diavolo told MC in the Devilgram Demon Lord's Castle Tour.
Diavolo also mentioned in said Devilgram that no one knows just how deep this pit really is, but it's possible to see "a glowing blue light at the bottom" if one looks carefully. Beside said lake is a tall gazebo, which Diavolo himself built when he was young, as he told MC in the same Devilgram. He also added more greenery and a stone path around the lake, because when he first came across the courtyard, it was "in a terrible state of neglect."
Secret Garden[edit]
In the Devilgram The Secret Flower, it was mentioned that this area is off-limits, presumably due to the types of flowers it contains.
666 Mysteries of The Demon Lord's Castle[edit]
Alongside the rumored 666 Mysteries of RAD, it is mentioned in Lesson 22-A (NB) that there are 666 "mysteries" related to the Demon Lord's Castle. Such rumors include:
- A mirror at the end of the east hall sometimes can have white hands reaching out for those looking into it.
- A door that opens on its own, no matter how many times it's closed.
- A mysterious handprint outside of a window fixed into the wall that's too high up to be reached.
