You spawn on a savanna peninsula, with open sea within about 400 blocks on nearly every side and the mainland joined behind you. A ruined portal sits about 201 blocks north of spawn, and a shipwreck lies about 258 blocks south. The surrounding water is mostly lukewarm ocean, with a river and stony shore within about 100 blocks. Badlands, jungle and desert all appear on the mainland, though the stronghold is a long trip at about 1487 blocks.
