|allagian (n., adj.)|
|Applies to||sourced headmates|
Allagian is a term for a headmate, usually an introject, who had a different gender, orientation, or similar identity before becoming a system member than they do now that they are one.
Their previous identity is called their pre-allagian gender/orientation/etc. and their current identity is called their post-allagian gender/orientation/etc.
For example, an allagian system member may have been pansexual before becoming a system member, but is asexual now.
From the Greek allagí meaning “change”.
