One of the White King’s great assets – even though he possesses a fallen Angel in his ranks was his belief that faith alone would not save his army and the art of both mechanoid and wizardry could always be relied upon to be great allies when administered carefully.
Hence the reason the king kept Universities that studied the mechanical and more unorthodox majical arts.
It was through these academies principled by the Queens Bishop that the flank engines were created…
Due to the massive size of mechanoid monster that is the Steam City it is slow to prime and start and is restricted in it’s movements at first. To counter this a small army of Blasters were created.
Incredibly fast initially on take off they eventually maintain a much slower speed up the battlefield.
This sudden burst of speed can surprise the enemy and give the impression that the mother ship is capable of the same acceleration.
