Eden was the name of a factory which was built in the Victorian era.
Eden was entirely invisible from the road. It was covered with creepers and weeds and had an epic and magical look. It had huge walls and narrow windows. Rustic machinery glimpsed within its huge towers. The factory looked like a cathedral, dedicated to Victorian industry.
It was the place were Joseph Montague built the Difference Golems. (AUDIO: Children of Steel)
