The area around Loyu Street was originally one of the most unnoticeable areas in all of Arlo. After all, this area was the goblin and dwarves' district. They weren't popular in this country of magic, and the estate prices here were the lowest.
This was the Mage Country. Goblins' and dwarfs' engineering technology would always seem extravagant but impractical in front of the mysterious power of magic—like a firework, beautiful yet otherwise useless.
"Engineers' cannons? Goblins' explosives? They don't even have the power of three-circle magic spells, and it's so easy to accidentally injure oneself with an explosion. Most importantly, they're really expensive, really heavy, and really unreliable."
"Goblin harvester mechas? A Silver-rank can easily deal with the small ones, while the large ones require astronomical prices due to the need for an energy source. Nor can large mechas be mass-produced, and I'm doubtful of their practical usability."
