Nekare` is, in her own mind, anyway, a perfectionist and an artist, and doesn't consider herself to be at all evil. Her one true desire in life is to reach the pinnacle of haut cuisine and share the experience with as many people as possible. She wants to connect and to belong, she's aware of her own talent and believes it to be the best if not only vehicle with which to achieve that. Her cannibalism stems directly from this, it has driven her down the foodie highway well past the last exit to gourmet avant-gardes.
She understands that society frowns upon the consumption of sentient creatures, but she believes that to be ignorant folly and an unreasonable deprivation of the senses, as the great side effect of intelligence is the huge range of emotion humanoids especially are capable of, emotions which, according to her research and experimentation, add a great deal of substance to the flavor of the flesh depending on what the meal was feeling when it was slaughtered.
Her Conjuration specialty offers as much flavor, no pun intended, as it does mechanical diversity since it literally gives her access to fresh meat w/o the difficulty of maintaining a a stockyard, although she'd still prefer to have the latter as emotionally preparing a meal before killing it is one of her greatest innovations. Still, with access to the many delicacies the planes have to offer, dishes like braised leg of glabrezu and angel heart scampi become possible.
Her ultimate goal is to see a world where her accomplishments are honored and where food is not caged by petty, misinformed morality.
