#sorry if this answers nothing but ty mimble for the excuse to gpose her more diabolical side

Silly question, but does Yasumi have a second name? And is her heritage Dunesfolk or Plainsfolk?

Curious why you'd ask, Mimble. Hmmm~~

Well short answer is not really. Granny Yasu doesn't follow traditional lalafellin naming conventions because she probably wasn't a lalafell to begin with and Yasumi is only one of the names that aren't her original name but people saw fit to call her (Hingan wife used it once to describe how she made her feel, so she kept it.)

Longer answer re: her heritage is a bit of an oc lore dump.

She was born an Amdapori child (probably a hyur) with a name now lost to time. Her soul was used among many others' to power the guardian golems that would counter the Mhachi attack and she was consequently sealed in the same prison as Diabolos after the war. For the first 500 years or so that as they waged their own war in their own void bubble, he called her Kuribu (though it wasn't her own name so much as the amalgamation of all the Amdapori souls sacrificed to animate that particular guardian.) For the following 1000 years and as their initial animosity slowly turned into a sort of mutual empathy and then mentorship, he gave her a new name, Oriax, as well as the power that came with it and partial command over his legion.

Later when she was released from the void back into this realm she found she had taken on the features of what were once her people's enemies, the Mhachi Dunesfolk, carrying residual knowledge of their void magic passed onto her by Diabolos as well as her original Amdapori white and summoning magic.

No one was there to give her a lalafellin name, but Matoya did give her a proper Sharlayan name just so she could get her into academia, which she eventually despised and has long since done away with, the only remnants of which can be found scribbled in the margins under less-than-flattering doodles of certain Sharlayan individuals or cited in the footnotes of some books in the Gubal library..
