Grocer Mion:
He he... I found out about my brother!
My brother said he would stop by at the abandoned mines east of the village, and then go to the east end of the Dwarven kingdom to praise the work of Lucien. Then, he was going to go see the wide ocean on the northern coastline.
But if you want to find him, you will go through some difficulties! Good luck then! (That was some of the best free labor in a looong time. Hoo hoo!)
