Ever wondered how a peculiar's power actually works? Well, you've come to the right place! Here you can learn about the two different types of peculiar powers, and how they are aquired.
The first of the two types of peculiarities to be addressed here are what are catagorized as "aggressive" peculiarities. This type of peculiaritiy is activated by the peculiar him/herself, such as Emma's pyrokinesis , or ability to summon and control fire (and she isn't burnt by it either). It is known that by activating these types of peculiarities, it will attract the attention of any hollowgasts in the area. Other examples of peculiars with this type of ability would be Enoch O'Connor (which could be loosely called necrokinesis), Fiona Frauenfield (possibly agrokinesis), Althea (cryokinesis), and most likely every ymbryme (temporal looping) ever to exist in the realm of peculiardom.
This type of peculiarity is on all the time. The user cannot control it, and therefore cannot activate it, to a point. At the beginning of one learning how to use their peculiarity, what is named above is always the case, in all cases known thus far. However, once one begins to advance in the usage of their peculiarity, they will develop aspects that is in fact within their control. It is unknown if these latter additions affect hollowgasts, unless the peculiarity is directly related to them, such as it is with Jacob Portman . In the beginning, his ability to sense and see hollowgasts is neutural, although towards the end of Hollow City, he develops a stronger connection with them, which he can choose to "activate" or not. Another example of this is Olive, who floats constantly. If not for her weighed shoes, she would float into the sky and never come down. Her ability can't be activated or unactivated.
Physical Peculiarities are abilities that are built into the body, such as Claire's backmouth or how Hugh's body has adapted to store bees without harming himself.
Internal Peculiarities consist of powers that locked within the mind, like the ability to see hollows or dream the future.
