As Northern Noah became wholly transformed into a battlefield of the Undead Tribe, there no longer existed anyone daring to venture there in search of gold.
Most adventurers desiring to make money had no choice but to head further south to Greenberg, either to assist Greenberg in combating demons or to aid the Holy Alliance against the Noble Church.
As for the Noble Church, those who still existed had almost all turned into Half-Demons. Although powerful, their enemy, the Holy Alliance, was backed by several other countries; many high-level mages and magicians had voluntarily joined them too. Compared to distant nations, the Mage Kingdom and Dilante Mage Tower were actually closer to Dionysio, a country that had already embraced evil, therefore being more influenced by it.
If Greenberg and the Holy Alliance truly failed, they too would be doomed. Therefore, many mages and magicians went there to assist.
