Syselfic

Syselfic is a neurogender or xenogender related to being an elf headmate in a system. It is exclusive to systems, and may only be used by systems. One who uses this term may feel as though their gender is directly connected to being an elf, or feel as though their gender is effected by their elf-self.

This may or may not fall under sysmythic, depending on the situation.

History and Flag
