I've been working on creating a mod for minecraft based on the Stormlight Archive. I've already gotten some of the items made and am interested in creating a custom biome. This would be the shattered plains, which would look something like the picture below. I am unsure on how to approach creating a biome that will create chasms like that. Any help would be appreciated.

I don't remember where I got this Optifine from. I removed it and my game launched. Thanks for suggesting this I never thought that it would be the cause as it had never caused any issues before hand.

Sometime yesterday my Minecraft forge stopped functioning completely. I'm running Forge 1.8.0 right now with a few different mods listed below: [1.8]bspkrsCore-universal-7.01 BetterSprinting MC-1.8 v1.1.1 LunatriusCore-1.8-1.1.2.30-universal OptiFine 1.8 Schematica-1.8-1.7.7.140-universal I had been using Forge recently before this happened and it was functioning fine. Now it isn't and I have no idea why. I've tried re-installing Forge, Minecraft, and Java. Nothing worked. I'll post my crash log in a Pastebin. Can someone help me fix this? https://pastebin.com/b9pMgZTY
