Description
Malevolence appears as a purple, bubble-like substance that infiltrates a being such as a human, a malak or even an animal which, with enough malevolence would transform the carrier into a Daemon. The level of malevolence corrupting a person or a vessel's body determines what type and strength the being will become once transformed into a Daemon.

Malevolence has been mentioned multiple times by Magilou states that it is the darkness of the heart and that malevolence stirs daemonblight. Malevolence is impurities born from the negative emotions of humanity—and ultimately threaten the existence of natures, humans and malakims. In some locales, it is visible as a purple particle moving horizontally from a body. Only a Shepherd and those working in concert with them, through the power of the Prime Lord malak, have the power to purify malevolence.

All animals infected with malevolence can transform into a mythical being from inspired legends and mythology, or a more powerful and elder form. Examples are: a bird into a harpy, a dog into a werewolf.

Important factors such as environment, lifestyle, relationship, temperature, feelings, and emotions determine the appearance of a human or malakhim, unlike an animal, which will simply further evolve or mutate. There are also fixed-gender daemons. Some examples include Medusa, Echidna, and Succubus hellions, all of which can only be derived from a female human or seraph
