Boan

The Boan are a historical Human ethnicity and a modern ethnolinguistic supergroup. The Boan were recognized as having pale to fair skin and very light hair tones. Modern ethnicities recognized as being descended from the Boan include the Rouhai and Ulfknapa.
The exact migratory pattern of the Boan are unknown, as they only first started appearing in the historical record around the Invasion Era. Some theorize that this means that the Boan were vistants, but others dispute this claim. Regardless, the Boan were first observed inhabiting the Underdark, which gave them a better ability to see in low-light conditions than other human ethnic groups. Sometime around the Invasion Era or Era of Restoration, a group of Boan migrated to modern day northern Tuatha, becoming the Ulfknapa.
