You spawn in a huge, open and flat grass landscape. Closeby there is a savannah which also is incredibly flat. Sure, there is some mountains on the sides far away but for the most part the seed is flat.
If you continue straight forward from where you spawned then first you will have to walk through the lengthy flat landscape but soon you’ll see a village. The first thing you probably will pay notice to is a tunnel at the beginning of the village which leads down to a cave.
