With this seed for Minecraft 1.16.5/1.15.2 you will spawn on an unusual mushroom island, which is surrounded on all sides by mesa. This island is located at coordinates -2800 ~ -1300. Oddly enough, here you will find a deserted village and a desert pyramid, which is quite rare in such an biome. Also, on this island there are many mineshafts that come to the surface. In general, there is a lot to explore in search of valuable resources.
