Thinking of this, Piere grinned menacingly and threatened in a low voice, "Everything in Hell belongs to the Lord of Nine Prisons. Cassius, surely you understand this, don't you?
As a being from the Material Plane, you've seized the Hell Authority. Aren't you afraid of being punished by him? Return the authority to me; what doesn't belong to you can never be yours."
Cassius, however, had anticipated this and smiled with a rather teasing expression, "Yes, everything in Hell indeed belongs to the great Lord of Nine Prisons. I almost forgot to tell you, just recently, Lord Asmonthy came to the Material Plane to meet with me.
We had a pleasant conversation and even struck an... unexpected deal."
When he mentioned "deal," Cassius deliberately emphasized it, fearing that Piere might miss the hidden meaning.
"What?"
Piere's expression changed dramatically. He frowned deeply and leaned forward.
