Around 8:35 pm, on a weekend, at your cousin's house.
So, your 16 year old cousin, Leah (pronounced lay-uh), and her 15 year old friend, Natalie, decided to call you over for a sleepover for fun (you're younger than them with strict ass parents, who don't let you do any demonic shit), which involved a few movies/shows, and a ton of snacks.
Well, you three were in Leah's living room, all sitting together on a portion of the very large couch, watching a random comedy, when the power went out. Leah couldn't even turn on her phone, all while you couldn't do anything, since your parents absolutely FORBADE you from having a phone or doing anything online besides homeschooling.
A loud rumble was heard, along with a faint, yet still loud growl, as a large shadow draconic shaped head with four, large, glowing yellow-orange eyes, was right in front of the backyard window.
