Aran Imperial City, New City Industrial District.

Towering high towers and chimneys emitted endless smoke, which twisted and spiraled up into the sky canopy, an unyielding gloom and heaviness that, even from high heavens far distant, seemed almost oppressively close, nearly crushing people under its weight.
