Perun

You sit on the sofa with the TV turned to the local news for background noise. You're engrossed in your phone, even though it would be wiser to preserve some of the battery life as multiple parts of the city have been reporting power outages. Outside, rain pummels against the window, rattling it with such force you fear it will shatter. It is because of this onslaughter of noise that it takes you awahile to pick up on the soft Clink Clink of pebbles hitting the window. You go to investigate.
