Probably Doma-specific. I am pretty sure the Ala Mhigan side is temporarily flush with money, after we liberated Theodoric's secret stash of gold and hair product.
I'm not sure why we still need to prove our abilities even in the Far East, though; the Confederacy should be well aware, as will people in the vicinity of Doma (ie Yanxia), and Kugane should have at least heard about us in some of the Job questlines, not to mention Kugane Castle.
I'm not even sure why we need to raise so much money in the first place (as opposed to leaving it to, say, Hien and the Domans). What have you been doing, Tataru?
EDIT: It is almost certainly tied into the Four Lords, I think.
Hell's Lid dungeon:
Jade Stoa (Byakko) trial:To wit, you are to venture into the hidden depths of Hells' Lid, a volcanic island once home to a host of oni─at least, according to ancient legend...
If the former does not lead into the latter, I will be very surprised.Legend tells of a peerless samurai who, at the behest of a king, ventured forth to drive a host of oni into the sea. Yet for all his strength, Tenzen could not do this alone, and so he turned to the Four Lords─greatest of the auspices─for assistance.
