In the special exhibit room of Warhammer World is currently dedicated to the Horus Heresy. One of the main exhibits and diorama's is that of Calth. This diorama in particular featured heavily in the art work for the 5th Horus Heresy rulebook: Tempest. It contains iconic images of the broken railway train, as well as dockland cranes being the backdrop as a deadly confrontation plays out between the Ultramarines and the Word Bearers Legions.
This diorama was smashing to see in real life, and my photographs probably don't quite do it enough justice. Equally, I think a generous smattering of dry ice and post-photography touch up was applied for the photos that appear in Tempest, so they're never going to be totally identical! Hope you like them!
