You can hear it again. That shrieking. That chittering. It grows louder as the thing you'd let escape returns, another like it following closely behind. You don't hunger for them, don't need to feed on them. You should leave. Still, the noises they make grate on you. They grind away at your nerves and burn in your brain, stopping just short of pain, and it would take you nothing to stop them. Just grab them. Just feed. Then they'll be silent.
You start towards the smaller one. It poses the least threat. It starts to shriek again, so you lunge at it. Thunder cracks. Lightning flies from the hand of the bigger one, and something pierces your shoulder clean through. You falter, fall to the ground, try to push yourself back up. Again, the thunder. Again, the pain. This time you feel it in your neck. Worse, you feel blood. Blood pouring from your neck and welling up in your throat, making you deel dazed. You won't be awake long, can't stand, can't reach them, so you spit at the face of the one that throws the lightning at you. As your blood hits it you hear the thunder again, and you black out.
Bars. When you wake up, that's all you can see. There's no more blood, no more pain, but there are bars. You try to grab them, to tear them open, but you feel something holding you back. Chains. They're trying to hold you, to lock you away. Not that it matters. You can smell them again, and the noises they make once again form a sweet, sweet harmony. You're hungry again, and there is food nearby. Nothing could stop you from feeding.
With a jerk, you launch yourself forward, ripping your chains from the wall. You find a lose spot in the bars and pry it free. Out of your cage, there's nothing left to stop you, or even to slow you down, and they're already so close.
You walk through a narrow passage, and three of them are there. One is lying on the table, the one who threw the thunder at you before. It's not moving, and its glow is fading fast. Another, the small one that led it to you, is shrieking again. You grab it, feast on it, once again falling into that state of sheer ecstasy. When you're done, there's only one left, and the two new children gladly accept their first meal.
