One From Elandor & One From Abyss

'A Demonheart? Is this the heart of a Demon?'

Instead of being surprised, Ian was confused since this was the first time he had heard about it. He already knew about the Abyss and abyssal creatures. He even knew about the Demons but had never heard of a Demonheart before, at least not in this form.

No matter how he looked at it, the Runeheart stone was nothing like a heart of any kind. 

From the description of the Quest, he could already guess it was indeed fragments of the heart of some strong Demon. Then again, why did Lyra need this to awaken her Abyssal Seed? Wouldn't it be too dangerous? 

'It seems I need to be careful.' 

As far as demons were concerned, their reputation was never good. They were always considered ruthless and cunning entities in Aetherion. That's why, although people wouldn't reject acquiring a demon bloodline, they wouldn't view it favorably either.
