Malificae is a gender that is in some way related to magic or witchcraft. It's up for the user’s interpretation, but it may have a magical or "witchy" feel. It may have connections to spells, sigils, rituals, and other types of magic. It may feel related to a specific path or practice of magic. For example, a cottage witch might experience it as being homely, cozy and related to nature, while a sea witch may experience it as simultaneously harsh and gentle, vast, and liquid. Malificae is a personalized gender so that means it's something different for everyone. One does not have to practice witchcraft to be this gender.
It does not have a suffix that can be replaced with a gender (e.g. it can’t be used as malificaexoy), but if paired with another gender, it may look like this: “I’m a xoy and malificae.” “They’re a malificae lykh, but they’re also juxera.” “Kit is a malificae girl.” However, it can be used as Malificaefluid and Malificaeflux, as well as Demimalificae, etc.
Malificae is similar to witchgender, however malificae is a more broad term while witchgender is a specific gender.
