The Island was created by me with Worldpainter. I made custom vegetation with cubical.xyz and painted them onto the island in Worldpainter. All buildings, paths, farms, and trees are custom and designed by me. I did not use any plugins such as worldedit, so all the man-made things on the island as well as all the custom trees were hand-made and from scratch.
NOTE: Feel free to modify my island or use it in videos or do whatever you want with it, just please credit me if you intend to publish anything containing my map or its contents. Thanks!
