Hero Summoning Error

## The Royal Temple and the City The story begins in the temple of the royal capital. A summoning circle is carved into the altar at the temple's center, and it lights up every time a Hero is called. Outside the temple is a city crowded with merchants, soldiers, and refugees. People call the border zone where the hush of the temple's upper levels meets the noise of the city 'the Upper Rim.' It's a place where prayers and the shouts of market hawkers mix in the same air. The temple handles rituals, records, and summoning administration, while the magic research halls and the training grounds for swordsmanship and holy arts stretch between the temple and the royal palace. The Hero's ten days of intensive training take place in this district too. The city looks peaceful on the surface, but conscription rosters are posted at every gate, and market prices rise and fall with the news from the front. It's a place where the word 'peace' and the reality of war always overlap.

## The Demon King, the Six Legions, and the Line of Heroes The Demon King has been slowly eating away at the continent for five hundred years. His true body is hidden somewhere far away, and the enemies that actually have to be faced are the six 'Six Legions' led by his lieutenants. Heroes through the ages have brought these legions down one at a time, and so far roughly one legion has fallen every five years. The nations of the continent are nominally under a peace treaty, but small battles break out on the borders every year, and national economies lean toward military supply. That makes the Hero a warrior and a symbol, and sometimes a diplomat too. A single word from the Hero sways public sentiment at home and the kingdom's credibility abroad. This Hero is an ordinary human summoned because of a one-letter typo on a form. Who knows this, and how much they know, comes out little by little over the course of the story.

## The Common Wisdom of Magic and Swordsmanship, and Its Gaps In this world, magic is a skill that consumes the body's energy. But the kingdom's education leans heavily on reciting incantations and repetitive drilling, and never teaches consumption rates or limits in numbers. Experienced practitioners just learn their limits by feel. Swordsmanship is the same. Engraving fixed forms into the body is everything; principles like the direction of force, distance, and angle are never explained. So efficiency only ever gets explained with words like 'talent' or 'experience.' That gap is exactly where the Hero can dig in. Modern thinking like measuring mana regeneration rates, calculating distance and timing, and breaking a command structure into small units doesn't exist in this world yet. The Demon King's legions don't seem to understand the concept of efficiency either. But the resistance of the traditionalists, and Kingdom Law, Article 1, Section 1, 'non-refundable,' keep the Hero bound to this world.
