Forbidden Knowledge

Forbidden knowledge, also referred to as the apocalypse, is a form of knowledge that does not belong to Teyvat. It is a form of "truth" that cannot be understood and is constantly rejected by the world. Because of its alien nature, this knowledge has ill effects on objects and living creatures alike.
According to Greater Lord Rukkhadevata, forbidden knowledge originates from the very bottom of the Abyss.
==Overview==
Forbidden knowledge was first introduced to Teyvat by the Dragon King Nibelung, who hoped it would turn the tide in the struggle against the Heavenly Principles. However, this knowledge proved to be massively destructive towards the world and its inhabitants, causing the heavens and earth to nearly collapse before the Heavenly Principles cast down the divine nails to stabilize the world.
Two more known surges of forbidden knowledge have occurred since Nibelung brought it to Teyvat. The first happened in the Great Red Sand several thousand years ago, when King Deshret pursued forbidden knowledge in an attempt to rebel against the Heavenly Principles. The second was during the cataclysm five hundred years ago; while the details are unclear, it appears that Khaenri'ahns also sought forbidden knowledge in order to defy the rules that the world under the Heavenly Principles were subjected to.Interactable: Someone's Abandoned Letter...Of course, I am keenly aware that the four pillars of our kingdom have achieved the prosperity they have today precisely thanks to us spying upon secrets from beyond the skies...
