During a recent stream, I made the observation that Rheoryn was "gender variable", but that in truth I had never seen her be anything but female and herm, and asked her if she had, in fact, ever been male.
According to Rheo, she was male, once, long ago; a little male jackal necromancer.
Now, amusingly, as chance would have it, due to various circumstances, Rheo stepped away after answering this question, and so she was completely unaware when I started sketching out a slinky, very cute little male black-backed jackal. It was only when she came back later that she was rather boggled, commenting that details-aside, it was like I had managed to sneak a look at the description of her old character.
