A new biome similar to the far lands.

I dont have a cool name for this biome yet, but I think it would be cool to have a biome with a greyish, swampy vibe generating around 10,000 block away. I think it would be cool if there would also be a mob that would be protecing some valubal resources and loot in this biome. A greyish barren wastland would be such a cool addition to the game, I think it would bring more adventure aspects to the game.
