Well, those who followed me in my previous gallery maybe could have an idea of who is this character and for those who is the first time that seen her I will introduce you to her.
Her name is Cariin, she is an old NPC I used to play as some sort data font for the PCs.
Her history is quite long, so I will resume. She was born as a dragoness many centuries ago (of course I'm talking of time into the campaign scenario) and she was layed in the same egg that her sister. Of course, in my world when two dragons born from the same egg, one becomes the evil twin and the other becomes the good twin. So, Cariin raised up developing a huge hate against almost everything, reason why the elder's council decided to banish her to the darkest point of the world. Once there, she fell into the edge of the abyss where she stay as prisoner for many more centuries and she suffered a transformation to a demon. After a long time of torture and suffering she had a chance to escape when a group of valiants adventurers dare to enter to the guts of the hell to rescue to one of their friends.
I guess it's all I can remember,. I made a change in her outfit and her eyes and horns.
