A few days later.
Red Agate Plain in the west of York County.
"Rumble..."
"Rumble..."
"..."
The sound of rumbling thunder echoed across the plain, continuous and unending.
At the end of the plain, visible to the naked eye, a torrent of steel surged forward.
The steam boilers chugged loudly, with hundreds of tall chimneys puffing out white steam.
Upon closer inspection, they were dozens of large and small mechanical fortresses.
The mining industry in the East Wilderness was very developed, so many movable machinery cities were built.
These steam-powered machinery cities were the private property of the lords, serving as movable cities on the wilderness, and also as reclamation tools.
During wartime, with a bit of modification, they turned into well-equipped war fortresses.
A few mechanical cities pieced together could form a large city in any region, capable of both attack and defense.
