So, I recently purchased my second adoptable character from Ninja-8004 on DeviantArt.
She's a sultry, enigmatic demoness that I have decided to name Dahlia. Pronounced dah-lee-ah.

Dahlia is a particular demon woman with a past favor for social chaos and disruption. As she would disguise herself as a mortal woman, Dahlia enjoyed making others hesitant and doubtful of their choices, whether minor or major, and questions them regardless of how they respond.
In the past, Dahlia has successfully spread false gossip and rumors of other mortals and demons alike, influencing them to oppose one another and engage in reckless or awkward outbursts amongst individuals of different social standings. The worst it has ever gotten was an entire city going to war with itself because of lies she has spread that altered over time to be used as a call to arms against not only the nobility, but multiple organizations within that city, too.

Dahlia has since calmed down from such events, since the type of distortions she enjoys aren't on the level of politics, espionage or warfare, but for more personal outcomes that aren't as likely to lead to the outstanding destruction of homes, workplaces, and entire castles. Or the loss of other citizens. If too many are away from her, then she has no means of hiding among others and will be spotted by experienced clerics or other highly-skilled mages that can see through her disguise with an ample amount of concentration and will very likely attempt to chase her until she is permanently dealt with.

Currently, Dahlia is 207 years old (out of 1,000 years for demon folk, as they become adults at 50 in this context). Behind her mask, she has a small nose with small pointy ears, with her eyes having yellow pupils and black sclera. The insides of her eyes can change at will from being round to being slit-eyed.
The mask itself is enchanted in such a way where it conceals a portion of the user's face, yet the user can clearly see through it with no visual issues.
Her current disguise is that of a pale-skinned 27-year-old woman with black hair and blue eyes. With the used name for her as "Natalee Shanbello".
Her true form is 6 feet tall while her disguised form is 5 feet tall.

Dahlia also doesn't seem to have good physical combat experience. She tends to depend on her demon magic, charisma, acts of deception, agility and stealth to keep herself from any unwanted danger.

These days, she tends to keep to herself in her garden among an unassuming house, on the fringes of a nearby city. But every now and then, she may indulge in a bit of social interaction (and disruption) with other mortals of interest.
