" Thunder rumbled, and it rattled the branches of the trees and shook deep inside the huge rocks, and the rain fell with cold violence. It was late afternoon, but it was dark as night.
A trail of lightning speared across the clouds, and Shadow wondered if that was the thunderbird returning to its high crags, or just an atmospheric discharge, or whether the two ideas were, on some level, the same thing.
And of course they were. That was the point, after all. "
― Neil Gaiman , American Gods (American Gods, #1)
