Cartonia

You turn to face more helpless beings only to find these ones don’t look so weak! They are covered in some kind of large body armor and carry shields and guns, although you don’t understand what these might be. You launch yourself at them bouncing off their shields and earning startled grunts from them. They quickly recover and shoot at you. A strange energy arkes out from them and you feel emense pain before all goes out and suddenly you are, again, no more.
