Commoner Magic Utilities (Anime)

Despite the Nobility's monopoly on magic tools that actively rely on the use of mana, there are a variety of lesser magic tools that are used frequently by the more affluent commoners of Ehrenfest. Since commoners are incapable of channelling mana into magic tools, those made for them require the ability to hold a mana charge that needs to be replenished regularly by a mana wielder. Furthermore the lack of mana of commoners also means that they can only register with a magic tool by stamping them with their blood. Notable examples for this practice are magic contract, guild cards and citizenship medalions.

The manufacture, maintanance and charging of magic tools for commoners is an important source of income for layscholars.

# Contract Magic

Contract magic is most often used to prevent nobility from taking too much advantage of commoners. The contract itself is written on special parchment with special ink that appears blue writing with it, but names written with it turn black when the name is stamped with the blood of the signatory. Once all members' names have been signed and stamped the contract will burn up and take effect..

When a contract between a noble and a commoner is signed, only the commoner have to stamp their signature with blood. Nobles can use a pen-shaped magic tool that will infuse the signature with their mana while they write it.

The range this protective magic has depends on the contract that was signed. Most commonly magic contracts only take effect within the city they were signed in, but more costly contracts that cover an entire duchy or even the full country can also be created, though the higher the range, the more costly a contract becomes.

Should one party fail to uphold their end of the contract, they will face magical repercussions. In the worst case this can even mean death. The consequences for breaches of magical contracts are not limited to just the signers, but can also affect people who were not involved and didn't even know of the contract's existence. For this reason contract magic is strictly regulated and every magic contract requires the permission of the archduke.

Such contracts can either be terminated by all signed parties' consent, or can be nullified at the discretion of the archduke as part of their jurisdiction.

# Citizenship Medal

Upon reaching the age of seven, the children of citizens take part in a seasonal baptism ceremony that officially designates their status as citizens upon completion. As they enter the temple, they are asked their names and have their fingers pricked to stamp their blood onto metal medals, at which point the child is officially recognized as a citizen.

People who were not born in a given city can also gain citizenship, but this requires them to pay a fee. If the person in question has close relatives that are already citizens of the city, this fee is reduced.
The fee also depends on the city they wish to live in, with bigger cities usually requiring a bigger amount of money, with the capital city of the respective duchy naturally being the most expansive.

# Magical Locks and Doors

As the main coordinator between nobles and commoners the Merchant's Guild in the City of Ehrenfest has been outfitted with a magical lock on the outer door and a magical door that completely disappears if touched by an authorized guild card between the second and third floors. Both were quite easy to open for nobles, since they were only meant to impede commoners and thus didn't contain any sophisticated protection against magical tampering.

They require regular recharging with mana by a layscholar.
