Marcy and the firing of clay

What if the box didn't send the girls across dimensions, but time instead? This work explores the scenario in which it sent the girls into the stone age, right into the world of Earth's Children (by Jean M. Auel)Read as Marcy works toward helping the people who find her into the next historical ages! Good thing she watched a series about this on Toob lately, it's technology speedrun time!(Currently undergoing edits, because i misremembered some stuff about the Sharamudoi. No major plot will change but like some locations and/or details.)Ok so perhaps i discovered the youtube channel primitive technology and kinda got inspired by my own old prompt for this AU.Sue me.Except don't actually please, i can't afford a lawyer.Can be read separately from the rest of the series Prehistoria.
