[Reasons for Kidnapping?]

"A pure half ghoul's blood is strong enough to destroy an entire continent."

A small pause. And then I looked back at Elliot for a moment. The black hair fluttered against the wind, while her pale red eyes looked at me with hope. Even though her expression was filled with anxiety, I could see that she wasn't fear stricken as before.

Smiling at her, I waved my hand for a few seconds before turning back to Navia and asking,

"Is it related to potions and such? Something about a chemical created out of her blood?" 

Navia's eyes widened for a brief moment before she nodded and continued," yeah. Though, there is a lot more to that but that's the fundamental part of it. You can take it as a [Potion of Destruction] that has many functions, but honestly it has far more uses than that. And obviously it is tempting, not just to the ghouls and vampires but to lesser species like humans and such."

'Guess so,' I agreed with her.
