Minecraft wiki entry for Nether_survival, associated text: One of the safer biomes in the Nether. This biome is mainly inhabited by a mass of zombified piglins, but is also inhabited by piglins, more rarely. The piglins are scared of the zombified piglins so the piglins should not be an issue most of the time. This biome is known to be flat and easy to explore, which makes it perfect for building. Since this biome has exposed netherrack on the surface, there is more easily accessible nether quartz and nether gold ores than any other biome. You can build a gold farm, which is extremely useful.
