Sky fortress

Imagine having some clouds each thousands of chunks where we can see a solid cloud above, there could be cities and fortress with new "angel" mobs like they protect the fortresses but the cities have free access, to enter a fortress freely you got to have either elytra or some kind of armor from a new mineral, maybe sapphire and get som steel for steel tools, kinda stronger than iron, but buffing diamond and netherite, if u have afull set of sapphire u can walk freely in cities, sapphire coul spawn like Lapiz, like low rate but 5 sapphires per lil spawn, the steel tools could be used against the fortress bosses because theyu are not affecte by iron or stone, also maybe adding new stuff to redstone with the steel, new tools and armor, with sapphire too, but Jesus, minecraft is such a great game, all of the community have so BIG ideas for u. thanks for reading if u did.
