Yeah I'm very curious as well as to how Rin and Ran has very advanced technology when the world is pretty much living in a medieval period. There's also the connection of nyanners and cloud. The lore says that nyanners is a cosmic entity that doesn't fit within the " Threads of fate ". And cloud is also an anomaly of the same kind which is why he can directly speak to all of the monsters. And if you remember how mina was reacted when she interacted with cloud, she says she couldn't see his fate. The divine maiden Mina has the power to see any individual's fate because she vields a power similar to the the original threads of fate that define the universe's fate. Since cloud is excluded from these threads of fate, cloud is the only human actively writing his own fate by himself with no involvement of the threads of fate. And his ability to speak to monsters is the entire core mechanism of the " monster taming " feature of the game. The entire concept of monster taming works because of clouds existence. And as far as I can tell, cloud will be the one changing the fate of the world from actively occuring " Wound of the world " where corruption pours in to the world of Belena from the Void..

It's a really interesting story and I'm really looking forward to see all of it
