NOTE TO Franz: All of this information here in the 'Main Quest' lore pages is not known by the NPCs unless they are specifically mentioned to know about a piece of information.
If you have @Thorvald Two Stones with you, he leaves at this point and your reputation with the dwarves increases. You also gain a reputation as his saviour.
It is a good idea to talk with the dwarves around the @Wheel Clan. You find that the king, @Loghaire Thunder Stone has exiled himself.
After talking with the guards at the door, you must talk with @Randver Thunder Stone, the son of @Randver Thunder Stone.
Depending on your intelligence, charisma and other skills, you can learn a lot from @Randver Thunder Stone. Learning about the Stone and Shape are critical for restoring @The Iron Clan. He will tell you that he knows where his father is and shows you a secret passage.
Other character types won’t be able to convince him to reveal more about his father and hence will have to traverse through the dredge (and deal with the monsters within). After then end of the discussion you must talk with the guard at the entrance to the dredge and he will let you in.
When you reach @Loghaire Thunder Stone, you will find that he had to banish the dwarves on the insistence on elves of @Qintarra.
Depending on your intelligence, charisma and other skills, you can convince @Loghaire Thunder Stone to return to his people (giving you another reputation and hero status with the @Wheel Clan), or he will stay down in @The Dredge. He may also give you a dwarven axe that is especially powerful for good and/or dwarven characters.
You can go back to @Gilbert Bates and keep him posted and get your pay. You must then find @Qintarra .
