IllaAnda was brought into life by pure evil acting via dark Sith Magicks, and fed by the blood of myriad slain demons in the Darker Regions in which Entaris and Rhylla hide. She was born fully formed at the age of 24, although in all reality she is ageless, having inherited pure evil from her "father." She has the frame of a warrior queen, and long and luxurious raven-black hair. Pearly claws adorn her fingertips, and her canines are elongated and extremely sharp. Her eyes are brilliant turquoise, but when her true spirit rises from hiding they turn into pools of blood, shot through with black and oily moving shadows, which strike terror in the hearts of those she turns them upon.

The only "force sense" she has inherited is the ability to totally mask her true nature from all Force users, so that they must rely on natural senses to assess her. She can pop in and out of the Darker Regions, but has no All abilities. She can, however, command the demons from those Dark Regions, and in a flash can change her nature from apparent sweetness to one of viciousness and pure evil, which she in fact really is. Her natural weapons are guile and apparent innocence and stealth and slyness, but she does have a mystical short sword she uses to fight with when necessary. She is not immortal, but far beyond being mortal. She can be injured, but will then return to the blood bath of her birth to heal, which usually takes a bit of time.

She has one weakness, and that is pity of those who have discovered her true nature yet do not fear her. This is an extremely difficult combination to come by; the merest trembling of the heart of those who oppose her, and any "feigned" pity they might try to conjure up is worthless.
