Ilsandra was lucky the city she stalked was always alive with music no matter what time of day it was. Even when they slept, the place had an eerie, calm soft kind of sound that echoed into the streets from these weird metallic cone-like things that were dotted around the city.
In the mornings, a siren would sound to awaken the human populace, and at night, the shift of the music from loud to gentle was the signal for it to be 'bed time'. They were like a well herded group of sheep that did as they were told through the signals of music. The only thing both cycles of the sun had in common was before each day began and ended they recited the words: "All hail his majesty and Supreme Vampire Lord, Azrael".
