Copy it into Minecraft 26.3 (Java).

You spawn in a Forest at the bottom of a valley, with the ground at least 40 blocks higher in most directions and the highest rim about 92 blocks above you. That crater-style mountain ring is the draw, and an Ancient City sits only about 47 blocks to the north-east of spawn. A Ruined Portal lies about 283 blocks south-east, and a Village stands about 341 blocks south-west, surrounded mostly by Savanna.
