Rion is a gender in the Aecor System in which one's gender feels like a river. This could be a xenogender in which one's gender is connected to or influenced by rivers, or it could be considered a form of multigender in which one feels faunagenders or kingenders related to the river ecosystem. These include buggender, lizardgender, froggender, ichthyogender, and more. Rion may also be a genderfluid identity, in which one's gender feels like a coursing river that never feels exactly the same. It is very similar to arroyan, except that rion is more vast and feels larger than arroyan. An arroyan person may only identify with a few non-xenic genders that they fluctuate between in a less significant way, while a lochen person may identify with more, and the changes in gender may be more significant.
Rion comes from the Spanish word for river, río.
Rion was coined by Fandom user Double-bi, also known as James, on January 2, 2021, in addition to the rest of the genders in the Aecor System.
