Arthur thought of the "Phantom Realm Sphere"!
Or more accurately, he thought of the last sentence in the remarks of the "Phantom Realm Sphere": the treasury of Baron Norvia!
Arthur couldn't be sure if the "Gentleman Thief" Carmen had successfully taken what he wanted from Baron Norvia's treasury, but on reflecting upon his interactions with Marinda, other than that treasury seeming to be related to the tiniest clue about 'Cat Hole. Nine Lives', nothing else seemed likely.
It couldn't possibly be related to the egg tarts made by Marinda's cook, Mary, associated with 'Cat Hole. Nine Lives', right?
That would be too far-fetched.
"Baron Norvia?"
Arthur silently recited this name in his heart.
Unlike South Los, Seberlin, Ainhars, Bert, Inner Bay, Rosha, and Sidon, where seven noble families equally divided the "Inland River" and acquired a great amount of tax through coastal trade to develop their territories and arm their armies, ensuring a stable life for the civilians within.
