Wow, I'm impressed that you know so much about norwegian traditions! Faarikaal is pretty simple to make, and hearty comfort food. Reindeer: they're free range and cover quite large areas, as they prefer different areas for the calving, winter feeding etc. Keeping reindeer herds in these traditional and protected communal grounds is only for people of Sami origin. But you can keep and raise reindeer on your own land if you like.
