Put on the ring.

You pick up the ring, staring closely at the intricately sculpted silver. The large red stone draws your attention, you swear you can see fire dancing within the gem. A general warmth radiates from the ring, your hands heat up reminding you of holding a cup of hot chocolate on a snowy winter day. Pleasant and comforting. You hold the ring between your fingers hovering over your left hand. It slides over your ring finger, and the stone glows for a second. You realize the ring resembles an engagement ring on your left hand. You decide on switching it to your right hand, but when you pull on the ring it refuses to budge. It doesn't feel like it's stuck, it just refuses to leave your hand.

"Come to me..." a low gravely voice calls out around your room. You look around but see nobody.

You check your phone, maybe you can get a hold of your friends. They'll know what to do, or maybe one of the boys from school can help you get to the tower. Your phone won't turn on. That's odd. Is it dead? It should be charged. Were you knocked out that long? With a quick glance around the room, you notice everything electronic is off. Your alarm clock, your tv, even the overhead light is completely off. You look out the busted window, and see the street lamps are all out as well. The red sky illuminates everything, so you hadn't noticed the lights missing until now.

So calling your friends is out of the question. But they were supposed to be meeting at your house anyways, so if you wait here long enough they should show up. In the meantime perhaps you should search the house for useful items. Something to defend yourself with in case you're attacked on the way to the tower. Or perhaps you can try out the supposedly "magic" ring.
