Concepts for Radiance, with the White Emperor and his pilgrims. The White Emperor rules from the Throne of Kae Aran, guiding and punishing his followers as he pleases. Being the most powerful radiant on the planet, his powers are immense. 

Color in Radiance is fun to do since it has an actual impact on the story: the universe is monochrome except in parts where the Radiance, a type of magic, is being used. In such cases, 'true colors' start to appear, which the characters can see. The Emperor is powerful enough that any color can appear around and mix into white - hence his name of White Emperor.
