Among my favorite Sartarite tribes are the Dundealos and their Pol-Joni kin. About a third of all the Storm Bull cultists in Sartar belong to one of these groups. They also worship Eiritha as the Cattle Goddess. Although the Dundealos are mixed-agriculturalists, the Pol-Joni are pastoralists. From about 1618-1625, the Dundealos were exiled from their lands by the Lunar Army and lived among their kin in Prax.
After the Dragonrise, they have recently returned to reclaim their lands from the “squatters”. They are as a result the most unsettled tribe in Sartar, and likely are still working out their tribal arrangements.
They are also the tribe most strongly associated with the White Bull spirit society of Prax, and are a stronghold of Argrath’s support in Dragon Pass. I suspect it actually surprises most spies when Argrath is accepted as a member of the Colymar Tribe in 1628. Most assumed he was Dundealos I bet.
