the thing with "redguard history and their heroes" is that it contradicts various other, newer, pieces of lore. hell, it even contradicts itself.
The singers packed their lives, folded their tents, mourned their dead, and followed Hunding to the great port city [of] Arch, in the province of Seawind. There Hunding had a flotilla of ships waiting. The Singers left their desert for a new land. No longer welcome in the desert empire, they to be sung about and spoken of in legend. The final great warrior, the singers of Shehai, the Book of Circles, all leaving that land where their virtue was unappreciated. Red, red with blood they were in the eyes of the gentle citizenry, never mind that they had saved them from a great evil.
this is just...wow. first, the names. second, the "red with blood" Redguards. third, the Redguards not appreciating skill in battle. fourth, the Sword Singers being some sort of clan. Fifth, the Redguards being "gentle." sixth, the pervailing idea of the totally good ansei and the totally evil emperor.
what i am trying to say is that these stories clash in lore and in atmosphere with everything that came after. The basic events are true enough, but the details and the feeling does not match.
