Mana-Technolgy

Mana-Tech
Mana-Tech, also called Magi-Tech, refers to the fusion of magic and technology that powers the modern world of Shinseina. Unlike traditional machinery or electronics, Mana-Tech does not rely on wires, electricity, or other sources of fuels. Instead, it runs on mana, mana crystals, runes, enchantments, and inscriptions.
Everything from communication devices to household tools is designed around channelling mana.
At its core, Mana-Tech functions by tapping into the ambient mana of the world or by drawing power directly from specially refined mana sources; these sources can be natural or artificial. Designs often incorporate a blend of magical aesthetics and practical engineering due to this.
While Mana-Tech has brought modern comforts to cities, such as lighting, indoor plumbing, communication tools, transportation, and much more, its reach is limited by location, wealth, and even political control. The knowledge and materials needed to produce and maintain Mana-Tech are considered somewhat expensive, and as such, access remains somewhat restricted.

Utilities
The development of Mana-Tech has drastically transformed the infrastructure of major cities in Shinseina, but this transformation is far from evenly spread, Mana-Tech is known to thrive in large populated places; while in smaller locations it is often more limited.
Cities equipped with Mana-Tech boast magical plumbing, lighting, heating, transportation, and even communication. These utilities are powered by mana crystals, sustained through enchantments, or controlled via rune-script interfaces; most are connected to the Mana Grids of the city.
These magical utilities are not easy to manufacture, their construction requires a blend of engineering precision and magical expertise, meaning only a group of skilled individuals, known as Manacrafters, can create or repair them.
In contrast, most villages and frontier settlements lack access to such luxuries. Without mana grids or wealthy patrons, their utilities are rudimentary or non-existent. Some may rely on communal crystals or simple mana-tech that is widely spread, but overall, life in the wilds is much more traditional.

Class Divides
While Mana-Tech has the potential to revolutionize life in Shinseina, its benefits are far from universally experienced. Access to this technology is sharply divided along lines of wealth, status, and region, leading to a widening gap between those who live in Magitech-powered cities and those who don't.
The cost of Magitech is steep. Mana crystals alone are expensive to mine, refine, and enchant, the engineers capable of producing Mana-Tech are few and in high demand. As a result, most advanced devices, and technology are limited to nobles, rich merchants, or guild elites.
Even among clans, the distribution is uneven. The Human Clan leads in Magitech development and accessibility, while other clans often either limit their usage to tradition-bound contexts or focus on entirely different magical crafts.

Personal Mana Interfaces (PMIs)
As Magitech continues to evolve, its integration into the body, mind, and daily function of individuals has given rise to some of the most groundbreaking and controversial advancements in Shinseina. Nowhere is this more evident than in the development of Personal Mana Interfaces (PMIs), Magitech Prosthetics, and Constructs.
A Personal Mana Interface is a semi-sentient, rune-coded construct embedded or worn by a person, allowing them to interact with nearby Magitech device, or manage their own mana flow. Think of them as a magical operating system that can "speak" with enchanted tools. PMIs can:
-
Display personal information and magical diagnostics.
-
Remotely control runic vehicles or mechanisms with permission.
-
Translate various known languages and information.
-
Link with city-wide mana grids for secure travel, identity, or messaging.
Though revolutionary, PMIs are expensive, personalized, and difficult to craft, often requiring a lot of money to purchase; and proper installation into the brain. They are rarely sold outside of Yokoso.

Regulation & Control
As Mana-Tech advanced, so too did the need to control, regulate, and restrict its use. Powerful enough to disrupt the balance of cities, clans, and even warfare, Magitech is no longer just a tool, it is a weapon, an identity, and an economic pillar. That’s why nearly every governing body in Shinseina enforces Tech Regulation Laws, with wildly different interpretations and methods.
Each major clan (and many cities) have Tech Courts or Regulatory Boards; official bodies that oversee:
-
Who can buy, sell, or own specific Magitech.
-
What types of enhancements or constructs are considered legal.
-
What level of augmentation a person can receive before needing approval.
-
Licensing of engineers.
-
Export restrictions to rival factions or enemy clans.
Some areas ban certain types of Magitech entirely, such as combat-grade PMIs, necro-tech, or autonomous constructs. Unauthorized possession or use of restricted Magitech is punishable by imprisonment, essence-binding, or fines that would bankrupt most.
