((Well, I made a char, I guess I start? If not ignore me, I am really bad at this things))
Nahx starts by shattering his part of therock planet, creating an incredibly strange landscape, like a broken glass. Then he creates hidden entrances to a set of caverns were his followers will live. All of this made from (rock), though he does put a few meters of soil over it all, and creates a rain of seeds (life), while also making water slowly leal from inside the shattered terrain. Of course, the caverns don't get flooded.
(So at the end it will become a really humid, jungle like place with a lot of caverns under the weird terrain)
Edit: fixed some stuff.
