WIP: Young Dorchasachian woman possessed by the spirit of her vengeful twin sister Siobhan who was murdered. Siobhan's possession of Eidaoin affects Eidaoin similar to Multiple Personality Disorder - except that there's pretty much two women inside one body, although Eidaoin has dominance 90% of the time as Siobhan only really appears in traumatic, stressful, or dangerous situations. Siobhan's personality is much more hostile and aggressive than the gentle Eidaoin.

Eadaoin travels the realm in search of somewhere she can feel like she belongs. Ever since her sister, Siobhan, was killed, Eadaoin's felt rather like she were only half a person. Losing the reassuring, doting presence of her twin sister made it quite difficult to function, but Eadaoin does her best and enjoys learning new things.
Unbeknowst to her, however, Eadaoin had actually been possessed by her overly-protective sister's spirited a short time after she was murdered. While she is aware of Siobhan's presence now, Eadaoin feels rather disconnected from reality and is afraid that she will be seen as a weirdo worth little more than ridicule and disdain.

The two sisters have very different personalities and skills. Eadaoin struggles with self-confidence - Siobhan was always the go-getter - but perhaps having her sister around again might help her get over that.
