Nithnirith

Nithnirith is an enigmatic being that exists as a lesser-plane entity. It resides in and rules over the Plane of Lust, having acquired it during the Plane Wars, and has since expanded her conquest for power and... Whatever it feels like doing, into the material realm, through her avatar.

Appearance
Nithnirith's true appearance is unknown, even to herself. Soul Yu'karin, being the most connected and most in proximity of, describes the Nithnirith in the Chamber of Lust (in the Plane of Lust)'s appearance as "a swirling vortex of various shades of red and pink."

The Avatar of Nithnirith, a physical manifestation caused by the transformation of Yu'karin Navacc through a constantly maintained, complete and total cross-plane bodily possession over, is an approximately six foot sheet-white Tiefling with red eyes.

Personality
Nithnirith is an odd mix of cunning and klutzy. She has expressed intentions and interactions ranging from the sly and underhanded to the ditzy, accidental, airheaded. Despite this, she maintains a moral standard and tries to keep everything on the ethical side. Where she can.

She is a sympathetic person, especially for a devil prince and will try to weave her deals around the core component of helping others... Usually for a price, however, in some cases such help for others can benefit her naturally, such as those who wish to become a citizen of the Plane of Lust. Nithnirith wishes to corrupt as many as possible through lust or some kind of other action or agreement which furthers her personal advancement in her home realm somehow. Nithnirith, while cited by many as an incredibly evil being, is honourable through and through, she will always follow through on her deals, unless the other person does not. Nithnirith would never agree to a deal that involved pledging allegiance, unless it were temporary and very beneficial for her. That would be her only stipulation.

History
Prior to the Plane Wars, Nithnirith was an ordinary citizen in the Plane of Chaos, an ever-shifting land that constantly and inconsistently changes every individual aspect of itself. When the Plane Wars began, she began a flash conquest of the Plane of Lust, concreting her leadership of it and then maintaining it. She developed the Plane of Lust into a surprisingly civilised society, a utopia compared to the material plane, albeit with it's downsides.

Once everything settled down, she turned her sights to new and seemingly random projects, some of which completely meaningless, while others extremely unsettling. Some of which are random pacts to those who appeal to her in the material plane. One of such pacts has become very beneficial for her and has resulted in a mechanism for which to further extend her follower base into the material plane.

Abilities
Being what she is, Nithnirith is capable of powerful offensive and utility magics, some of which she even created herself. She is even capable of allowing others to use the spells she created.
