a crotchety old lady who runs a third rate orphanage

every time a sick or injured child comes through her door she accuses them of faking it for free food

and the reason she does this

is because the kids inevitably turn out to be fine in a few days

because she is unaware that she is a mythic Radiant with healing powers

so she heals the sick and wounded without realizing it

then sees them healthy impossibly soon and goes "I'm getting scammed again"

is THAT what was up with her?

I skipped over the novellas in my last reread because there was already so much

yeah she's a radiant

she was always trading dun spheres for lit ones because she was draining the stormlight out of them

Right she shows up as a minor character in the main series later but I didn’t quite remember what her deal was
