Hunters Guild President Bernard:
To be honest with you, I opened an investigation after our last conversation. With the help of my guild members, I found out where a lot of those coins are hidden.
The best I can tell, the Rakin in the southern area of Aden, the Vanor Silenos and the Timak Orcs of Northern Oren have coins.
I'm not sure who else has them, but reliable sources tell me that some can be found on Oren's bandits, in the National Cemetery of Aden, Dragon Valley, the Land of Atrocity, the Garden of the Beast, the Valley of the Saint and the Battlefield of the Past.
