The Rings of Power tells the story of a group of Harfoots, including Nori Bradyfoot, during their "Wandering Days." This was a time when they moved around a lot, including when they crossed the Misty Mountains.

And based on how the landscape is changing and what we can see of maps, it looks like the Harfoots are definitely moving east, towards the Southlands and what will become Mordor.

We also know that, according to the prologue in The Lord of the Rings by J.R.R. Tolkien, no one knows why the Harfoots moved over the Misty Mountains and into Eriador.

But it's thought that it could be because men are moving into new places and evil is growing in Greenwood (later renamed Mirkwood).
