There was a reason why demons like Achyls weren't supposed to know what Heaven was like.

Demons were the epitome of everything wrong in the world—all of the grief, all of the sorrow. Their hands were made to destroy, their tongue to carry out plagues. There was nothing good in the existence of demons. In fact, they were omens, harbingers of damnation.

Yet, in spite of all of that, Achyls had found salvation in the taste of you. And greedy as he was, he wanted more.
