Sorry everyone, I've been moving house and struggling to get an internet connection at all, which is somewhat sucking. I've come into the university in my town and used a computer, so here I am.
So...you've collectively gone off to do research. I'm not going to make anyone roll, because most everyone else is looking for ruins of weapons caches and more violent sort of places.
You can easily books regarding the Shogunate and its manner of dealing with agriculture (they're the very dusty tomes hidden at the back that hardly anyone seems to read). Inside are revealed very detailed explanations of how the Shogun organised the feeding of such a large area as Creation, and the systems that transported food around. It mainly seems to comprise of technology from the First Age that was refitted and adapted to serve the purpose. It also comments on how relatively quickly this technology degraded without the First Age Creators to maintain it. There are some designs and plans for relevant technology, from the warstrider-esque robots that store and move food whilst defending it to boxes that are unable to be opened, except by the one person who sealed them.
One particular piece of technology that will probably catch your eye is a spider-like device. Standing around 4 ft tall with spindly legs, it has a chest of about 2ft x 2ft x 2ft, and is designed to travel across difficult terrain. Notes near it claim it can float in water and act as a small boat. It is recorded as being a storage device for personal items of a Twilight from the the First Age, but the Shogunate deemed it a waste of energy to extroplate its uses any further. there are similar items of practical use listed as being used common-place by people to store and transport, though often to the frustration of the higher-classes who didn't understand their fascination with 'useless' trinkets.
The book was written towards the end of the Shogunate, and records places of massive food stores throughout Creation, as well as places of interest. One of the medium sized-granaries is located within the boundaries placed upon students.
I'll try and come back and check in 36 hours or so what you've decided...
