Wandrel moving fort
Developped by Wandrels, based on librarian technology, Moving forts are said to be the safest, easiest way to move merchandise from one town to another. These hulking vehicles, that have become a staple of the Great Roads in the Sheherp and the Middish Plains, are often as tall as a dozen men, just as large, and even longer. Because no carriage could efficiently move such a behemoth, the forts use the modern Ghostpowder motors technology to move. They travel slowly, barely faster than a walking man. However, they do not stop, not even at night or to refuel. As a result, they have now become the main actors of merchandise flux between cities. In addition to being massive trading vehicles, moving forts are also a precious military asset for their owning wandrel families. A trading vehicle can easily be armored and adapted for warring purposes, and vice versa. As a military vehicle, a moving fort becomes a mobile base of operation. It is both an impenetrable fortress, and a powerful siege weapon.
