Gregg smells like chemicals. That stingy formaldehyde kind of smell, with a touch of strong herby stuff. Also the smell of the streets. If he walked by, you’d probably smell it.
Qatö probably doesn’t smell like anything otherworldly, though sometimes after using his element he does smell distinctly like burning stuff.
Dartak smells like someone who goes outside a lot (not sweaty but that strong leafy kind of smell).
Swift smells like someone who lives outside a lot and adventures. And that probably entails smelling like mud and dirt and dried blood and sweat. Wonderful.
Ala smells like the sea.
Ado smells of perfume, of varying sorts. She probably smells very clean, of her soaps and such.
Thomas smells like dust and shame.
