You spawn on the floor of a forest valley, with ground at least 40 blocks higher in most directions within about 700 blocks and the highest rim about 68 blocks above you. That ring gives the start a crater-like feel. A Ruined Portal sits about 171 blocks south-east, and an Ancient City lies about 675 blocks due south. Three villages are within about 640 blocks, and cold ocean and taiga lie beyond the rim.
