Copy it into Minecraft 26.3 (Java).

You spawn in a Dark Forest at the bottom of a valley, with ground at least 40 blocks higher in most directions within about 700 blocks and the highest rim about 99 blocks above the floor. A Ruined Portal sits about 183 blocks south-east, and an Ancient City lies about 333 blocks due north. A River is about 64 blocks away, with Birch Forest close behind, so wood and water arrive early.
