Titan moon of saturn like Realm or Biome

The moon of Saturn called titan has a core of silicate rock. The next layer us a special water ice called ice 6 found under extreme packed pressure. The next layer is a salty ocean with a thin layer of icy crust. The surface is covered in organic material. This material could be a orange to black and is similar to mycelium or nycelium. Its rain is sand and liquid. This could be the key after a couple of major updates for a new realm requiring a special portal. It can be created using crimson or warped logs coated with bonemeal making the colored lines white like the fungus. The it can be opened by breaking an endrod on the portal and can be places upright and on the ground. In order to break the rod you have to break it on that created block. The portal has to be 4x4 and both portals have to be broken in order to reset a localized chunk spawn for either side. The realms vegetation can be ice based and fungal based. In retrospect the surface has no hostile mobs but mobs from other realms are attracted to the location once the portals open and act different. The portal can be unlit using redstone and relit as long as the redstone connection never breaks.
