Faced with such a direct question, Demitri had nothing left to hide.
He sighed and began to explain these "underground businesses."
"In fact, I shouldn't have known about this," he said, "but Roman trusted me to manage them... Everything is as you heard from Savia, we... we sell items from relics on the black market, sometimes mechanical constructs, sometimes rune books, sometimes even Fire Seed and Floating City components. Each relic has different products, but since they all bear a strong Northern Land style—rough, ugly but durable—no one thinks they are smuggled goods from other countries. Instead, they are believed to be the private work of Gittilers."
Dylan was somewhat baffled, "Wait, Fire Seed, Floating City components? Are you saying that all the technology related to the Floating City—except for the casing—comes from underground relics?"
Demitri opened his mouth, somewhat fearful of meeting the gaze of this younger man.
