Ashara stood atop of of the round, dusty stacks that made up Kumogakure's mass, looking down on the village that was splayed out beneath her. They had fought off the last Samurai assault, leaving them no time to take their bulky cannons with them, leaving the Kumo ninja with more than thirty metal weapons that very few of them knew how to operate. And it had fallen upon Ashara, one of the three Sanjin, to place them in strategic locations. Mind working quickly, she considered the weapons' range and radius, having seen them in action during the clashes with the Samurai. She would have to set the village smiths to making cannonballs, and for that they would need moulds, supplied by the earth-element users. But the moulds would need to be made of a rock dense enough to resist the heat of a smelter, and for that they would need to search deep underground. The cannons would be most effective at taking out enemy siege equipment, or tearing into slow-moving ranks of armoured men, but most Shinobi were fast and perceptive enough to dodge them...
Ashara clutched her head, irritated. Why couldn't Yoki have sent one of his generals to do this? She concentrated, skin turning to paper, and a clone of herself melted out from her back. It would be her mouthpiece, since she could not speak without hurting her throat. The clone placed a hand on her shoulder, facing the men assigned to her workforce.
Okay, it said loudly. For starters, place a cannon on either side of the main gates. From there, set one up every fifth of a mile along the walls, facing outwards. Any that are left will go on the stacks within the walls, to fire on troops that have managed to breach the perimeter. Operating them isn't too difficult; you just clean out the barrel, place a new ball inside, replace the fuse and light it up. And aim, of course.
Ashara clapped her hands, and the men got to work.
