The Great Calamity, or just the "Calamity", was a world wide disaster caused by the Supernatural beings that provoked the division of Hitara and subsequent torpor of the Pachamama

"I will send for your priests to bring them your word and hand you a nation of souls" - Abijah Fowler

The Great Conflict is an ongoing battle for control between the Deities, the Wardens and their proxies, the various supernatural and humanity.

Essentia is the primordial "Life-force" that makes up the universe, or to say it in another way: It is the strings that harmonize the inhabited world. To be able to "resonate" and know how "touch" this strings is to be able to manipulate and influence reality, matter, and even the minds of others.

Unbound generally make the comparison that the world is a great instrument where they can play any and even create new notes and songs thru their Schemata, but with the disadvantage that they need to know how in order to not produce vulgar acts of Anacorde. While the other supernaturals are only able to approach this instrument in a fixed delimited way thru codified, often inherited, taught or bestowed abilities called Disciplines or thru another medium like with a Facade.

Also called Judgment Fracture or Kairópsis, is the primordial maddening violent fear left in the souls of pure Mortals by the Calamity. This madness occurs every time a supernatural manifest their powers in an open manner or appears openly without a "mask" to all pure mortals to see, it causes them to go psychotic and be overcome by an irrational fear that screams at them they need to kill whatever is violating their world view, provoking them to either go berserk and become reckless or run away. While this desease can be resisted by share will, the lucidity of the subject will only last for a certain time if the supernatural being is not killed quickly. If the subject manages to survive the encounter with the supernatural being after falling to dread wake, they will not remember anything afterwards, only being left with the sensation that they had a stroke.

While the full effects are seen in the field, in much greater scale the effects of the Eidolon Fracture can be seen in the reluctance by pure mortals of wanting to acknowledge the existence and happening of supernatural phenomena by trying to rationalize and mask a supernatural event as some other more common occurrence like a fire, explosion, plague or etc.

Thanks to the Wardens the Dreadwake also affects recordings and some technological devices.

Kairópsis is the reason as to why so many stalkers say that dealing with the supernatural is an uphill battle with one self rather than against the anomaly.

Dreadwake caused by Nahuals can sometimes lead to a mortal becoming Kinfolk.

Those mortals who manage to resist it and kill the supernatural will see their humanity damaged in some way.

The Unshackling is the perilous process that a normal Mortal can go thru in order to awaken to the full extent of Essentia of the world. Those Mortals who have become or have been born touched by the supernatural cannot manifest their Unshackling since they already are aware of and can touch the Essence of the world thru limited forms. Only true pure Human souls can become Unbound.

Depersonalization is the consequence of an Ochema loosing all of its humanity. They basically lose sight of who they are and become an automatous Rabashak-adyr hell bent on devouring and staying alive. In Simulacra depersonalization causes them to fall victim to a dementia like state that makes them resentful and insane.
