No words are necessary when you mix iconic images.As per previous discussions I am thinking "Less is more".
And as Chaos has a mixed time-line vibe of warriors from back and forwards through time, I figure that famous or iconic scenes of destruction or fire could be photo-bombed.
Rome and London burned, and major established civilisations have crumbled.
There are plenty of iconic visions of future apocoli ?..umm..Apocalypses.
Chaos insignia and proxies could be among hieroglyphs and the Sphinxes.
Mayan and Celt prophecies of "the end", can be used.
A Mayan calender could easily hide or scream Chaos, and if we can get an animal trainer to deal with the beast, we could even use the Viking Ragnarok
This is my personal gauge at the moment - http://www.kittyhell.com/wp-content/upl ... ainsaw.jpg
eg. Does an idea seem as evil yet fun as that chainsaw ?
