Glaciesian 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 ice. One may feel like their gender is specifically related to ice, or they may feel that a certain aspect of their gender can relate to certain aspects of ice. For example, someone may feel that their gender is related to ice if their gender feels strong, cold, and beautiful, yet fairly airy and not dense or intense. Glaciesian people 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 glaciesian person who is fiaspec could say they're rhosynic glaciesian, from rhosynian.
The term 'glaciesian' comes from the Latin word 'glacies' meaning 'ice'.
