Awakening

One moment I'm walking through the city, the next, I wake up in a world that shouldn't exist-prehistoric, brutal, raw. The early Stone Age. I don't know how or why I'm here, but I do know one thing: I can heal from anything, but death still lurks around every corner. One wrong move, one slip, and I'm done. Between the wild beasts, the primal tribes, and nature's merciless grip, I'm a modern man in a time where survival is a daily battle. My only advantage? I can regenerate. My biggest weakness? I can still die.
