The front cover illo is a dynamic forced-perspective piece:
The front cover depicts a bird's-eye view of a FEMALE SHADE KNIGHT
riding on the back of a SHADOW DRAGON IN FLIGHT. Both of them are made
of translucent shadow (i.e., you can see through them), and it's very
important that we find an artist capable of doing this sort of
transparent effect. The dragon is wearing a black bridle, and the shade
knight is wearing a cloak over her armor. She grips the bridle with one
hand and holds aloft a gleaming longsword in the other. They are racing
up toward us, and the dragon's jaws are agape.
Behind the shade knight and its mount, we see the TOP of the CITY OF
SHADE, as if we're high in the sky looking down at it. The city is
built atop a gigantic floating rock, suspended above a dark sea. The
city's dark towers angle toward us, but they should still be relegated
to the background; consequently, most of the city can be hazy or
half-hidden by clouds. Also, the city and clouds should be lit in some
color, like orange, because the creatures in the foreground are dark.
