Stone age

(So I got this idea while thinking up a dnd campaign) In this world its more of a fantasy stone age. It has cavemen, cavewomen, ancient orcs (nothing really different about them at all), ancient elves, ancient dwarves, prehistoric animals, fantasy animals, and monsters of all sorts. You're part of a small tribe that lives in the northern part of the continent where its always pretty cold. Your tribe consits of about 60 people all with different roles. The main threats to your tribe are hunger during winter, Yetis, White dragons, and some of the other tibes located near your tribe. (Gender, name, age, race, role in tribe, ect is all up to you)
