Biosphere

Biosphere is a terrain generating mod created by Risugami. It generates worlds that are made up of massive spheres with glass domes. Inside each sphere is a random biome. There is a random chance of a lake being placed in the center of each sphere, usually water, but rarely lava. Bordering this lake, players can find sand for Water or gravel for Lava. Connecting each sphere is a wooden bridge with a fence rail. Beside each sphere is a smaller sphere where Diamonds and Lapis Lazuli can only be found. Other ores are equally spread throughout the spheres. The cave generator used here is a modified Nether cave generator, where Lava generates below a certain level; if it reaches the outside, an Obsidian wall is generated to hold it in.
