“A person's shadow stood for his legacy, his impact on the world. Some people cast hardly any shadow at all. Some cast long, deep shadows that endured for centuries.”
“Some lights cast more than one shadow. Stand before nightfall and you'll see for yourself. The flames shift and dance, never still. The shadows grow tall and short, and every man casts a dozen. Some are fainter than others, that's all. Well, men cast shadows across the future, as well. One shadow or many." - Stannis”
“This is good, and all good things cast shadows.”
“Everything that is,casts a shadow”
“When walking through the "valley of shadows," remember, a shadow is cast by a light.”
“If a person cast no shadow at all, he couldn't be alive. His existence became meaningless.Execrating Apophis by destroying his shadow would cut his connection to the mortal world completely. He'd never be able to rise again. I finally understood why he'd been so anxious to burn Setne's scrolls, and he was afraid of this spell. (Carter Kane)”
