Who Is She?

Pitch Black and Death

Death was laying in the middle of her meadow, the sunlight pouring over her skin and warming her. She had been so afraid that she was going to freeze at North's place, no one would have been able to help her if she had frozen. She had to delay a few deaths to warm back up from the frost that covered her body and now she opened her blue orbs to see a nightmare approaching so she sat up.

"Hey there little one, such a pretty nightmare," she said softly as it stopped in front of her, it was a small one but anyone else would've been just as afraid of it as if it were a big one. Death pet the black sand that made up the mare's body, "I'm no longer afraid now that I'm warm, did you come just to visit me? I suppose I can send out the reapers for a while."
She focuses then snaps her wings out to their full width. A few long feathers falling out and turning into small, snake-like, floating creatures that flew off to sever the souls of the soon dead from the bodies. The nightmare was startled but Death calmed it as Pitch Black cautiously walked into the clearing of the forest that was Death's Meadow.
"Ah, the beautiful Death herself, I see you found my runaway nightmare," he says.

The winged girl shot him a glare that sent chills up his spine, "Watch it, Black, compliments from you mean nothing, you simply want something," she said.
"Oh but you are beautiful, though as usual you see right through me, I would like to have my nightmare back," Pitch points to the small nightmare that Death is giving attention to.
"You wouldn't come here for a simple nightmare, other ones have visited me before and this is only your second time here," she says, standing shakily, she was still cold and a bit weak but she tried to push that all aside as she walked to Pitch, "Give me one reason why I shouldn't kiss you and make you disappear."
"Well I'm not trying to end your existence like the Guardians or Life," he says.

Death sighs and turns away, hugging her arms as talking about Life was a touchy subject for her. To explain why she threatened with a kiss, the Kiss of Death is a real thing, she kisses a human's, creature's, or spirit's forehead and for the first two the soul is severed from the body and allowed to move on; for spirits, it ends their existence forever, no butterfly, nothing. She can choose when this effect will happen and when it won't, she's never done it to a spirit and she's never taken the soul of someone or thing who wasn't about to die.
"My apologies my dear, I didn't mean to upset you," Pitch says.

Death snaps her head around to look at the boogeyman, her eyes as white and cold as snow, "Never 'my dear' me and leave now, you know not to talk of Life and now I'm getting irritated so you'd better leave before I get angry," she says.
Pitch shrinks in fear then leaves, the nightmare chasing him.
