The world was like some anime far-future idyllic utopian sorta thing, an equal mix of shining silver cities along the coasts and uncontrolled wilderness filling the inland regions. Everyone was happy and free to do what they wanted. The only problem was that there had been a war several hundred years earlier, fought using OGREs (from the Steve Jackson game). For those of you not familiar with the beast, OGREs are huge robot tanks the size of a city block or two with about a million weapons on them. Occasionally, one of these beasts would shake itself awake, having spent a millenia disguised as a mountain or living under a lake or something, and start on a war rampage.
So we're picnicking at this dormant volcano crater many miles from town. Beautiful locale; little trails and scenic points and a lake in the center of the crater and all. Lots of people milling about, nodding pleasantly to each other, strolling along in paradise. And then the ground shakes a little bit and the mountain begins to shift, because it is actually an OGRE, a super-huge one, bigger than any ever before recorded-- it's the entire mountain, hundreds of feet tall, maybe half a mile long.
Everyone scatters. The OGRE is going to spend anywhere from minutes to hours listening for orders (which will never come) and then it will choose a course of action. Until it starts moving, we can get away fairly safely as long as we're quiet-- it already has anti-personnel weapons for targeting people but they are targeted by sound. Somehow, in the confusion, my family is separated-- my mom and the older of my two sisters aren't at the car when I get there with my brother and other sister. We drive around looking for them but cannot find them, and we don't dare call out for them because the OGRE will notice us. And it starts to move, as the mountain begins to slide away from it in sheets, leaving just the lake pooled on its back. I spin the car around and drive for the city, because we can outrun it, and maybe my mom and Kristi will make it to the highway on foot-- but I know, deep inside, they none of us are going to make it.
