I'm glad the global server admins have finally applied the 1.18 "Caves & Cliffs" update.
Like something out of a Jules Verne novel! Looking forward to updates if they find the new species they expect down there.
I wonder how many more undiscovered areas are there and how might they look. Would they evolve to be very alien and different looking given enough time?
There's constant input from the world above so it's probably not that different from the area around it.
