I don't know my version or loader
Crimson Chaos is a mod that adds a brand new dimension to the game. Accessing the Crimson Chaos dimension requires buildinng a portal out of Crimson Hyphae and lighting it with a Crimson Eye. This portal will send you to the Crimson Dimension, a massive place similar to the nether but about three times as large. The Crimson Dimension will have its own mobs, ores, vegetation and more.(Most of these are still in progress)
WARNING: This mod uses a world size that is significantly larger than normal and so it is recommended to have a decent computer in order to run it.
