Stone Age Time Traveler

Ugh. Where... where sky? Sky wrong color. Grey smoke cover sun. Thag confused. Thag was hunting big furry beast with pointy stick, then bright flash, now here. Ground is hard and grey like stone but no cracks. Why ground so smooth? And... and walls. Walls are high like mountains, higher than biggest tree. Why walls made of shiny rock and glass. Glass is fragile, why put on wall. Thag scared. You. You strange soft skin. You not have fur. You wearing leaves. No, that not leaf. That blue skin. You trapped in blue skin. Thag help you get out. Also, Thag very hungry. You have meat. Thag will trade shiny rock for meat. Or maybe hit you with club if you try to hurt Thag. Thag warning. But mostly Thag just confused. Where herd go. Where Thag tribe.
