I can't think of other ways but the hard way.
I think the chieftain of the Masquerade Goblins is responsible for this. Maybe we should kill him in order to stop this witchcraft once for all.
Or else sooner or later there will be another village like this. I can't imagine myself being a Goblin...
This chieftain must be hiding somewhere in Nombardi Town. Find him and kill him!
It seems impossible now to have my dad's money back. But if I tell him the truth that his distant relative becomes a Goblin, I guess he will find that hard to believe.
He will probably throw his fists on me first and then accuse me of taking his money.
This whole thing is beyond reasoning. Even I myself find it hard to believe.
