First, map out every angle the enemy could approach from, like a blueprint. Then stack layers of defense: a sturdy outer wall, a hidden trap zone, and a sensor network. Build each section with precision—check every joint, make sure the bricks fit snugly. Add aesthetic touches that still serve a purpose, like decorative archways that double as ventilation. Keep the layout modular so you can swap out parts without wrecking the whole thing. And test each piece under stress before moving on. That way the fortress stays solid, efficient, and looks like a masterpiece.
