Quote
...And it is told that he made his way through their streets at night, crawling through their many windows and crouching in their gardens, moving through the sewers beneath their cobbled roads and slipping over their railings. Watched by their cats and the roosting pidgeons of their city, yet wary of their slumbering dogs, he went. They would not see him, nor wake as he drew near, but would only shudder, softly calling out the names of their gods in sleep. Restless, they tossed as he passed under the window like an errant lover fleeing dawn. And by morning light he was gone, away from that place, and moved on to another world.
