T'ing Douzen tells you, "Salutations, I am known as T'ing Douzen, and I have been sent here by the Arcanum to collect the Aetherium Power Cores dropped by the Gear Knights, and the Aetherium Ore they've been piling up in their excavations here." T'ing Douzen tells you, "I am prepared to reward Adventurers of sufficient experience for their efforts in collecting 10 Aetherium Power Cores, and also for 10 Aetherium Ore. I only have enough supplies on hand to reward adventurers for one pile of 10 Cores and one pile of 10 Ores each per day."
