Xbr’aal lore?

[Ascended_Demon]

There's also Nitowikwe and Wawlika, who don't have Xbr'aal names but rather names similar to the other residents of Shaaloani.

There's actually a simple answer for this that we got before we even reached Tural. Races in Tural are named after the tribes where they are most predominate. Hrothgar in Tural are the most common race in the Xbr'aal tribe and that is why they are called that and the same goes for hyur being called Tonawawta in Tural. It is, in theory, possible for a Tonawawta to be part of the Xbr'aal tribe even though we do not see any. So given Nitowikwe and Wawlika's names we can infer they are, in fact, from the Tonawawta tribe and not the Xbr'aal tribe which tracks given that Tonawawta tribe originates in Xak Tural.
