Well.... when you're effectively immortal, barring sickness or grievous injury(and possibly even capable of recovering then), things become... interesting.
Meet Fari. That's not her true name, but it is her familiar name, and the only one she gives... because now she has an excuse to become impressively, horribly intimate with others. Appearing typically as a woman with a rather matronly figure, she stands no less than ten feet tall at any given time, when in a world where such isn't too odd, and six feet when it is, with long, red hair streaked with gold, and gorgeous silver-green eyes. Her skin is typically pale, as well, often marked with viridian lines, here and there, that have no apparent pattern and shift constantly on their own. This is her humanoid form, of course...
Being a lady of Chaos, and royalty thereof, she's not human, nor is she confined to any single form. She can shapeshift as she sees fit, assuming she has time and sufficient energy, not really needing sufficient mass though it does help. However, her shapeshifting abilities do come in handy.... after all, she can stretch quite a bit more than anyone would guess, and look rather a lot different if she so chose, as well. Gender, appearance... everything is up to her whim, really.
Now, what is she? Why... she's the rule of a little corner of reality all her own! Goddess of her own pocket dimension.... and if you wind up there, well... you're either the pet, or the meal. Possibly both...
Regardless. She's an initiate of the Logrus and an accomplished Shadowmaster and Sorceress. Add to that fact that she's got an artifact known as a spikard, and, well, she's not wanting much in the power department. Skill, grace, and speed when casting are essential, and she's had millenia to hone hers. She's not a deity in her own right, mind.... but she comes pretty close in many ways.

That image? It gives a good idea what she looks like, and coincidentally is one of her favorite forms for when she travels.
