Archbishop Karquen had more than one office, Mir learned. He had caught a glimpse of the one on the surface segment of the Church, and now that he was sitting inside the second office, his mind automatically made a comparison between the two and reached the conclusion that the former was pretty much a poorer version of this one.
Pitch black marble seemed to be a staple element of construction of the underground segment of the Church of Sunbreaker. It was not a commonly available construction material in Enet District, to Mir's knowledge. So he could only assume that the industry was hoarding the good stuff for the rich people to boost the elitism breeding in the minds of the denizens of underground cities.
