Seed Description: You will spawn in a grassy/sandy area. To your right will be a Mesa Biome. Go straight into the Mesa Biome and you will see a huge Mesa Mountain. Inside the Mesa Mountain, there are many tunnels (inside which there are a number of rare ores such as gold and iron), rails, cobwebs, and other objects. If you want to go exploring, you should either have a considerable supply of torches and a compass, or you should know how to duplicate items[link to tutorial on duplicating items]. If there are mobs in the area, you should also have armor and a number of swords.
Seed Description: You will spawn in a grassy/sandy area. Directly ahead (but nearby) is a sand village. There is a somewhat hidden blacksmith’s chest (you might not find it immediately), but it contains some valuable objects: 7 tree saplings, 3 emeralds, 3 gold ingots, 5 obsidian blocks, 3 iron ingots, and an iron sword.
