City of Ehrenfest

Ehrenfest (エーレンフェスト Ērenfesuto) is the capital of the duchy of the same name and it is the medieval city where Ascendance of a Bookworm initially takes place. It's ruled by nobles with magical powers and has a rigid class system. Buildings created by the Archduke or a member of his family with magic are all coloured in a shade of white.

The city originally consisted of only the area now known as the Noble's Quarter. When the first Aub of Ehrenfest dethroned the previous lord 200 years ago, the city was expanded to include the lower city as a show of power and wealth of the new lord.

Prior to the expansion of the city, the temple was originally an inn that served as a front gate while travelers were investigated. The gate that once led to the old city is now called the Noble's Gate.

The lower city is the southern half of Ehrenfest, separated from the northern half by the temple. The lower city is the location of the homes and businesses of the commoners; the level of quality of the buildings ranges from “rundown shack” to “grand manor”. The buildings are most glamorous and nice in the north and smallest and most cramped at the southern of the city, with a gradual gradiant in between. The rents also reflect this, leading to the rich and powerful to settle right next to the noble's quarter, while the poor live at concentrated at the southern edge of the city.

All parts of the city, whether rich or poor, consist of multi-story buildings with the first two levels being constructed out of an ivory-looking substance that was created with magic and extensions made of regular materials like wood and stone on top, some reaching as many as six stories plus attic high. In the poorer parts of the city the attics are often used to hosue smaller livestock like chickens belonging to the families that live in the highest story.

In areas with business the ground-floor is where the store or worshop is located, with the second floor being reserved for the owner and their close family to live in. The third floors and above are then rented out to either more distant family members, employees or if there's room left, anyone the owner approves of and who can afford the rent. The least luxurious apartments at the top of the buildings are often rented to live-in apprentices.

The lower city section of Ehrenfest does not have a school; instead, children receive an education in a particular career through a business apprenticeship following their baptism.

Due to a complete lack of plumbing it is common for citizens to just dump their waste out the window, leading to the lower city being constantly dirty and smelling bad. This is not limited to only the poor southern parts of the city, but also holds true for the wealther areas.

According to traveling merchants, this poor state of the commoner parts of the city is not a normal state of affairs in the entire country. They report that at least some other duchies have much clearner lower cities. In preparation for Ehrenfest increasing it's business contact with other duchies thanks to Rozemyne's new products, the leaders of the duchy decide to clean up the lower city, so that visiting nobles and merchants wouldn't get a bad impression from the state of the commoner's areas. Since due to the mana shortage evacuating the citizens for a day and completely re-building the entire part of the city was ruled out. Instead the Merchant's Guild has been tasked to hire commoners to manually clean the streets, starting with the main street running between the eastern and western gates since it has the most amount of merchant traffic. They also discussed implementing rules that require commoners to regularly bathe, but no definite decision has been made in this regard yet.

Spoiler from Part 4 Volume 4 As Lady Charlotte's scholars recently discovered, there had been plans to create a sewer system for the lower city utilizing sanitary slime magic tools, like the one in the noble's quarters and archduke's castle, but at the time Ehrenfest lacked the mana-capacity to make the changes with creation magic, leading to repeated delays until eventually everyone involved had either died or forgotten, with the blueprints left to gather dust for decades in the archduke's personal storage until their recent rediscovery.

Due to the time-constraints between the scheduled remodeling of the lower city and the expected arrival of the foreign merchants following the next archduke's conference, the nobles refrained from fully remodeling the entire lower city, since that would have ended up destroying all the extensions that were built on top of the ivory buildings. With the majority of commoners living in those wood and stone extensions, this would lead to large parts of the population loosing their homes until they can be rebuilt, leading to refugee camps that would undermine the attempts to beautify the city and drastically reducing the rate of production for the very products to be traded with other duchies for which the remodeling was decided upon in the first place.

Instead of this full remodeling, only the streets and underground will be remodeled, with the residential buildings staying untouched. While this will mean that the individual homes will not have their own toilets, bathrooms and waste disposal chutes, instead opting for communal bathing and waste-disposal areas like in parts of the temple, it will not only stop the mentioned disruption of commoner's lives, but also obviate the need to evacuate the entire population, since they can now take shelter inside their homes. It also reduces the mana-cost of the spell.

In addition to the sanitary concerns, at Lady Rozemyne's suggestion the remodeling will also add additional pipes for access to water for paper-making workshops, though the mana-intensive water purificaiton magic tools will have to be added at a later date, since the duchy lacks the regular mana supply to keep so many additional tools running at the current time.

Responsible for the security of the lower city are the soldiers of the city guard. In addition to guarding the city gates and acting as the local police force, the city guard is also responsible for cleaning the main roads of snow in the winter and cutting down Trombe that have grown too big for the scavanging children to deal with on their own. Soldiers of the city guard are recruited exclusively from commoner citizens and the entire guard is subordinate to the Knight's Order.

Should a noble be required to deal with other nobles that listen to the members of the city guard at the gate due to them being commoners, the gates are equipped with rott bells to call a member of the Knight's Order to deal with the noble.

To prevent collusion and negligence of soldiers staying in the same place the entire time, the gate guards are rotated between the city gates every three years. For this purpose the gate guards are split into platoons that move in their entirety to their new assignment, from the Commander down to the freshest apprentice.

The Noble's Quarter is located in the northern half of the city, separated from the commoners southern half by the temple. The Noble's Quarter is an opulent suburb, with all residential buildings being large mansions most having a big garden.

Like the lower city, the Noble's Quarter doesn't have a school. Tutors are called in to teach the children until they reach the age of ten. In winter they gather in the children's room. At the age of ten, children are sent to the Royal Academy each winter until graduation. A noble is only considered a true noble if they attend and graduate from the Royal Academy. This school teaches nobles magic related things and prepare them for social gatherings.

Unlike the lower city, the noble's quarter is being kept meticulously clean, mainly by the use of magic tools.

Spoiler from Part 4 Volume 4 Every set of rooms where a noble is expected to life or to house guests has their own toilet and bath and each building has a connection to the sewer system. Both the individual toilets and the sewer system utizlize sanitary slimes to dispose of the waste.

The Ivory Tower is a high-class jail exclusively for imprisoning members of the archduke's family should they commit severe crimes. The magical doors are configured to only be opened by members of the archduke's family, but once the door is open, anyone can enter. However entering the tower without the express permission of the Aub is considered treason and even members of the archduke's family can face execution, depending on the surrounding circumstances.

Currently the only inmate is Veronica, the mother of Aub Ehrenfest for faking an archducal permit and thus enabling an attack on the Aub's adopted daughter.

The Knight's Order is a battalion of knights who serve as the primary defense force of Ehrenfest. The Knight's Order is made up entirely of adult nobles who can wield magic. Knights live in the knights' barracks, located in the general area of the Archduke's castle, alongside several training grounds.

Karstedt is the current commander of the Knight's Order, though the former commander Bonifatius is still active in training knights even after stepping down.

Contained within the walls of the noble's quarter is an entire forrest, so that nobles can relax, hunt and gather magical ingredient in a relatively safe enviroment. Should feybeasts beyond a certain danger level be spotted, the Knight's Order will sortie to hunt them down. Once a year there is a great hunting tournament during the festivities surrounding the Harvest Festival.

The Ivory Tower is also hidden away in the forest.

Spoiler from Part 4 Volume 4 When Judithe ran out of rejuvenation potions she petitioned Rozemyne for a leave of absence to gather ingredients. Rozemyne took this as an opportunity to go to the forest with all her retainers under the guidance and protection of Bonifatius, so all of them got the opportunity to gather ingredients and for her guard knights to gain experience in guarding her against real dangers in a controlled enviroment. When he learned of this Wilfried requested to be allow to go along with his guard knights, which his parents granted.

Since it revealed some big flaws in the abilities of some of the apprentice knights, it was decided to make this a regular occuranace in the future.

The temple is the primary place of worship of the gods and contains the Ehrenfest Orphanage. It sits directly on the border between the lower city and the Noble's Quarter and performs Religious Ceremonies for nobles and commoners alike.

The priests adhere to a strict hierarchical structure.

The Archduke's castle lies beyond another wall separating it from the Noble's Quarter. It looks around three to four stories high from the outside and has much land surrounding it. On the land are several facilities for tutors and forest rangers to live in, training grounds and barracks for the Knight's Order and gardens for tea parties. The Archduke's family lives in the castle with their attendants. It has an entry on the northern side for private visitors and the Archduke's family themselves, and an entry on the southern side for workers.

The castle itself is also subdivided into several wings, connected by corridors.

The central building is where the Archduke and his first wife reside and also houses meeting rooms, ball rooms and similar facilities. Inside of the Archduke's office is a room that allows access to Ehrenfest's foundation magic. The northern building is where baptised children of the Archduke live until they get married. The connection corridor to the main building terminates on the second floor. Beyond the entry area, this floor is reserved for boys, with the third floor being for the girls. The first floor is only used by servants. The Easten building until recently was used to house the Archduke's mother, meaning it is probably reserved family members of the Archduke other than wives and children. The Western building is where the second and third wives live.

Prior to moving to the nothern building upon their baptism, the Archduke's children usually stay with their children, though in recent history Wilfried has been raised by his grandmother Veronica and accordingly lived in the eastern building with her until turning seven.

The meeting rooms inside the main building are divided into ranks so that a meeting room appropriate to the expected guest can be chosen, with the ones for archnobles being much more richly furnished and decorated than those meant for lower ranking nobles.

As the castle is big, there are many corridors and stairs which won't lead one directly to their destination. For that reason, Rozemyne is permitted to use her highbeast Lessy inside the castle so that she won't faint or would have to be carried all the time.


 * Suzuka has noted that the north side of the lower city would look like Rothenburg, Germany in the Manga Part 2 Volume 1 afterword.
 * Rozemyne's room in the castle is located directly by the stairs. It looks like her room in Karstedt's estate.
