Idaelius

Idaelius is an identity in which, over periods of time, you become a different person or thing. This usually includes having a different orientation/gender/pronouns/view of yourself and can also extend to different hobbies, interests, and behaviours. This can last for hours or months, and usually reverts back to the original person or thing. The person or thing you become may be fictional, or not. You can be an aelius of someone/something multiple times. Being idaelius is not caused by being plural, otherkin/fictionkin, or having delusions. Being idaelius can be caused by anything, so there aren't terms for when it is specifically caused by something, though the creator will give you permission to make those if you ask.

Externally, this may look similar to being a monoconscious system, where members share one consciousness and switching is more like 'becoming'. The individual knows, however, that they are not a system. The individual may still outwardly identify as plural/a collective/a system, as it is easier to explain. This experience can co-concur with being plural, otherkin/fictionkin, or having delusions, but it is not inherently so.

This term was coined by @B0YVINCIAN on twitter (@faerielogy on Tumblr). There is also a Carrd.

Terminology
An aelius is the person or thing you become (similar to alter/headmate in systems). A primaelius is the main/most prominent identity that one usually goes back to (similar to host in systems). A poetaelius is an aelius that is (based on) a fictional character (similar to fictive in systems). A veraelius is an aelius that is (based on) a real person (similar to factive in systems). An archaelius is an aelius that is not based on anything. Becoming is when you become a different aelius (similar to switching in systems). It was noted in the carrd that the coiner includes examples of systems only because they believe systems are more common knowledge, and that examples that already existing terms are easier to understand. https://idaelius.carrd.co/#section02

Idaelius and aelius are nouns. You use them like " 'i am idaelius. i was [x] for a week.' '[x] was an aelius of mine. specifically, a poetaelius.' 'i became [x] yesterday evening. please use [z] pronouns for me now.' "

=Flags and Symbols== ⋈ - bowtie

The coiner chose this symbol because "[he thinks] it looks good, and [he] had never seen it before so it would be very recognizable."

B0YVINCIAN: "the flag was inspired by my systemflux flag, which is a very similar concept from when i was trying to figure myself out. the symbol on the flag is a symbol that represents something called an identity in math, so it's kind of fitting. the colors were chosen at random so if someone wants to try to come up with meanings; go ahead."
