Destiny's Forge: A Dwarven Kingmaker Campaign
Breyda, Arbiter of Mourngrim
According to Druga Diamond-smile, who fought on her side against the Party, Breyda was an Arbiter of Mourngrim, who led her North from Bharakhdur under the auspice of assaulting the Party whom Breyda claimed had wronger her clan.
Apparently she was working with the Gnome, Pretelwiss whom, her—as yet unseen—Grandfather had originally retained to deal with the Party. Breyda kept on trying to deal with The Party, who she reportedly took umbrage with, even after her Grandfather may have possibly ceased attempts to hamper the efforts of expedition.
She may be of clan Greenpyre.
