Does anyone know which Pictish tribe Zogar Sag represented? I can't find it in any of the associated literature, including Across the Thunder River. I am assuming that Gwawela was in Eagle, Raven, or Hawk land; or perhaps Wolf? The map of Pictland and the Westermarck in AtTR does not show Gwawela, and the land around where it is supposed to be could be claimed by any of the aforementioned tribes. Any input would be appreciated, as I am reworking Beyond the Black River as an adventure for my PC's campaign, and would like to elaborate on these details. Thanks all!
