Knocky in Ebron. Her dialog is necessary before you get the dialog with the soldiers at the mine.
Aldin, city map, Mirel in party, blacsmith, elf. Next go to field in left site of Aldin city and to bottom, he will stand here, talk again, he will take you to hidden willage, in that willage, blacksmith (black haired elf girl in leather brown dress), talk when katryx ore quest active, next go to mine and talk to green suit soldier, go to whitestone citadel (if I don't mess the spelling) talk with capitan in sleeping chamber (green haired with glasses) go back to soldier and enter mine, it is green ore on other site of poison lake. i hope it will help
