Redhawk Caldera What exactly are we dealing with here?

"What the damn hell?" Dwin took a step back, when the stranger noticed her and came - no - drew - no glided closer to her. He had a very cold aura, did not have any smell that she could identify him by and she also did not remember his face. Even if she had met him during early childhood. She scrutinized him through narrowed lids, her muzzle wrinkled and responded his request with series of low, rumbling growls.

"Sorana has not been here for ages," she told, vaguely recalling the tall, young and very sad girl of Teya's last year's litter. She had always seemed too grown up (and - in Dwin's opinion - too arrogant) to be engaged in any of the fun games that Dwin played with her siblings. "She was very sad and then disappeared. But - who are you and why do you care so much suddenly?" she asked, her tone cold. 

The ghost did not reply and then a moment later Dwin was left on her own. It was as if the ghost had never existed at all.
