Loghaire Thunder Stone

Loghaire Thunder Stone is the self-exiled leader of the Wheel Clan dwarves, the dwarf responsible for the banishment of the Black Mountain Clan. Adding Loghaire to your party is an involved process. To start out, you must speak with his son Randver about the dwarven philosophy of Stone and the Shape. Getting the dialogue option for that requires 10 intelligence (you can simply boost it with an Essence of Intellect). Then, when you finally meet Loghaire you must discuss the Stone and the Shape philosophy with him to convince him to end his exile. Then he'll offer to join you after you've found out what happened to the Black Mountain Clan. He is another pure fighter type, specializing in melee and dodge.
