The world of Minecraft is a vast one, filled with numerous biomes, oceans, and deep underground caverns. In the Overworld, players can build houses, build farms, and fight mobs as they traverse these many unique biomes. However, theres more to Minecraft than just the natural Overworld. With a few obsidian blocks and eyes of ender, players can travel to alternate dimensions via portals to the Nether and the End.
