Cinderian is a gender in The Nadurian System, one of the four Nature Systems. It is a gender which is both connected to nature and its overall aesthetics but which has a specific and strong connection to fire. One may feel like their gender is specifically related to fire, or they may feel that a certain aspect of their gender can relate to certain aspects of fire. For example, someone may feel that their gender is related to fire if their gender feels very hot and raging. Cinderian individuals can have any alignment and/or no alignment, and depending on what alignment they have, they could use another term from The Nadurian System to describe themselves. For example, a cinderian person who is fiaspec could say they're rhosynic cinderian, from rhosynian.
The term 'cinderian' comes from 'cinder' relating to 'fire'.
