Denizens of the House

In the Keys to the Kingdom series by Garth Nix, the Denizens of the House are the inhabitants of the strange House that makes up the Center of the Universe. (Please note that this article excludes the Piper's Children, as they are really mortals who have gained Denizen-like qualities due to existing in the House for so long. It also excludes New-Nithlings, who are more similar to humans, except for the immortality they share with Denizens)

Description
Denizens are similar to humans in all aspects, with a few exceptions:


 * Denizens are nearly immortal.
 * Denizens cannot die of old age, sickness, or starvation while in the House, and are resistant to almost any injury; this also extends to Piper's Children or Mortals while within the House.
 * Denizens can only be killed with fire, superheated steam, or other things hot enough, certain weapons (such as the Commissionaires Clubs, and various weapons of the Glorious Army of the Architect), by a prolonged absence of their heads, by Nothing ,by a bite or scratch from a Nithling, which dissolves them into Nothing, or a Key to the Kingdom.
 * The blood of a Denizen is blue, and their bones are gold. (A possible similarity to Ichor)
 * Denizens are very resistant to change of any kind, and are often described a narrow minded or stupid.
 * Denizens are handsome, with the Denizens of higher House Precedence being tall and the most handsome.
 * As they were made solely for House management, Denizens are extremely devoted to their work, and nothing else.

House Fashion
House fashion changes every several centuries, as the Morrow Days decide it. It is currently an Earthen 19th century style, with clothing, food, and transportation of that time period. Dame Primus mentions that when the Will was ripped apart and imprisoned, ox-carts traveling up endless mountains were used as transport; and Suzy remembers having to wear a pointy hat at some point in time.

Notable Denizens
A few notable Denizens from the Keys to the Kingdom series, in order of appearance.

In Mister Monday

 * Mister Monday
 * The corrupt and slothful Trustee of the Architect, Master of the Lower House, Mister Monday controls the First Key and Monday in the Secondary Realms, and is Arthur's chief enemy in the first book.
 * Sneezer
 * Mister Monday's personal manservant and butler, Sneezer is briefly possessed by the Will and suggests to Mister Monday that he give the Lesser Key(the First Key can be divided into two seperate Keys, a Greater and a Lesser; an hour hand and minute hand of a clock, respectively) to Arthur. Sneezer appears in several other books as Arthur's butler after Arthur defeats Mister Monday; he is also the only one so far to be able to operate the Seven Dials, a way to travel into the Secondary Realms.
 * Monday's Noon
 * Private Secretary and Personal Cupbearer to Mister Monday, Noon is Mister Monday's most loyal servant, and is the chief agent in the hunt for Arthur in the first book. Noon is re-employed as Monday's Dusk at the end of the first novel.
 * Lieutenant Keeper of the Front Door
 * Guardian of the Front Door of the House, the Lieutenant Keeper appears in several of the books, and is a firm supporter of Arthur.
 * Monday's Dawn
 * Monday's Dawn does not have much notable activity in any of the existing books, but is present in Mister Monday.
 * Monday's Dusk
 * A strange, mysterious Denizen, Dusk wishes the House to be as it was before the Breaking of the Will and betrays Monday to help Arthur succeed in his mission. Dusk is changed to be Monday's Noon at the end of the first novel.
 * Pravuil
 * This demoted Denizen works in the Coal Pit as a Coal Collecter until he meets, swears loyalty to, and later betrays Arthur. A slippery character, Pravuil seems to be in the employ of the Morrow Days.

In Grim Tuesday

 * Grim Tuesday
 * Grim Tuesday is the avaricious Lord of the Far Reaches. Highly skilled at working Nothing, Tuesday makes a fortune selling his goods to the other parts of the House.  However, Tuesday can create nothing original, and must copy all he makes from the various Secondary Realms.
 * Superior Saturday's Noon/Dusk
 * These two characters ask Grim Tuesday to push a sorcerous pocket into Nothing at the beginning of the book on behalf of their master, and tell Tuesday about how he can strike out against Arthur, and claim the First Key. However, the two are not specifically named as Saturdays Noon or Dusk, it is merely implied. Both have appeared in several other books to date, with Dusk apparently being killed at the end of Lady Friday by the Piper.
 * Grim's Grotesques
 * Yan, Tan, Methera, Tethera, Pits, Sethera and Azer are the seven servants that Grim Tuesday recast from his original Dawn, Noon, and Dusk. They are skilled artisans, and their breath is deadly to mortals. When one is killed at the end of Grim Tuesday by supposedly Saturday's Dusk, they all die.
 * Japeth
 * A demoted Denizen who used to be a Thesaurus Minimus Second Grade, Japeth is introduced as a slave of Grim Tuesday, and is freed at the end of the book. Japeth helps Arthur defeat Grim Tuesday, and later writes an exaggerated account of Arthur's story entitled "Lord Arthur's Adventures".

In Drowned Wednesday

 * Drowned Wednesday
 * Drowned Wednesday, Duchess of the Border Sea,also known as Duchess Wednesday, Lady Wednesday, and (the "shied-away-from" name) Whale Wednesday. After consummating her role in the Breaking of the Will, she found herself possessing an uncontrollable desire to eat. She decided that to undo this, she must execute the Will. She approached Saturday for help, but was betrayed, and the other Trustees (Save Monday, who was afflicted with Sloth) took her portion of the Will, and limited her use of the Key to keeping her shape. She was then transformed into a white whale 126 miles long and has a mouth 10 miles wide, and forced into the Border Sea by the Morrow Days. After millennia of dwelling as a whale, devouring almost anything in her path, she decides to hand her Key to the Heir and relinquish the Duchy. This was done, although Wednesday herself was killed in the process.
 * Wednesday's Dawn
 * An arrogant, shape-changing official; the last living in-command figure to Wednesday, as Wednesday ate her Noon and Dusk. Abetted her Duchess in the relinquishing of the Third Key.
 * Sunscorch
 * A sailor on the Border Sea; the only competent sailor among a crew of Salvagers aboard the Moth, which rescues Arthur while on the Border Sea. Loyal to Lord Arthur; and becomes Wednesday's Noon after Arthur becomes Duke of the Border Sea.
 * Captain Catapillow
 * An ex-accountant; one of many such accountants who became sailors after Duchess Wednesday's submersion caused the Border Sea to overflow, turning many of the buildings into ships. A collector of stamps, dDied clinging to his collection as he couldnt take it with him while inside Feverfew's worldlet.
 * Doctor Scamandros
 * A Doctor of House Sorcery, which is a practice of magic that relies heavily on Nothing. Scamandros lost his final term paper before he could turn it in, and now seeks it in the Border Sea. He is the only Upper House trained sorcerer in any of the realms under Arthur's command as of Sir Thursdsay. He aided Lord Arthur in the effort to seize control thereof. Later was made Wednesday's Dusk.
 * Captain Elishar Feverfew
 * A cruel, once-mortal pirate captain who has so meddled with Nothing Sorcery that he is now part Nithling. Feverfew controls the worldlet inside Drowned Wednesday that the Third Part of the Will is hidden in.

In Sir Thursday

 * Sir Thursday
 * Sir Thursday is the Overlord of the Great Maze and the Commander in Chief of the Glorious Army of The Architect. He is adamant to the orders he receives from his superiors, i.e Saturday. While claiming to have no personal quarrel with Arthur, he states that he will neither release the Fourth Part of the Will or relinquish the the Fourth Key unless ordered to. He was defeated by Arthur, with the aid of Marshals Dawn, Noon and Dusk, and imprisoned within the Citadel.
 * Sergeant Helve
 * Helve is Arthur's immediate superior while he is serving in the Glorious Army of the Architect.
 * Corporal Axeforth
 * Axeforth serves as Arthur's Barracks Commander.
 * Bathroom Attendants
 * These servants of Saturday are responsible for the cleaning between the ears of Pipers children in order to keep them more docile.

In Lady Friday

 * Lady Friday
 * Lady Friday is the ruler of the Middle House. She sends one of her servants to Lord Arthur, telling him that she has given up ruling the Middle House, and relinquishes the control of it, along with the Fifth Key. The envoy informs Arthur that Friday has sent the same proposition to the Piper and Saturday; whichever of the three that reaches her Scriptorium and touches the Key recieves control of the demesne and the Key. All she asks is that she and any of her servants that go with her to her sanctuary be left alone. It is later reavealed that this was a trap designed to get rid of Arthur, the Piper or Saturday, or all three; as the "Key", when touched, opened a rift into the Void of Nothing. Arthur escapes, and wrests the Key from Friday's control at then end of Lady Friday.


 * Friday's Dawn
 * Friday's Dawn is the only of Friday's superior servants who do not accompany Friday to her Sanctuary in the Secondary Realms. He controls the Guilded Youths, a group of Piper's Children who have been fundamentally altered. He accepts Arthur's offer of control of the Top shelf and Binding Junction in exchange for his assistance in fighting Saturday's invading forces.


 * Friday's Noon and Dusk
 * Friday's Noon apprehends Leaf when she attempts to use his phone, and then puts her to sleep in Lady Friday. Dusk does not play a large role. The two escape direct punishment at the end of Lady Friday because they are "experiencing", a type of emotional vampirism, and therefore in a coma-like state.
