Ikkanu's shipwreck: Slight scent of sea breeze from the outside Sulani air. There would also be a slightly burnt smell indoors as he lights a lot of candles for various ceremonies and to ward off bad spirits. The strongest smelling room would be his bathroom because he likes his luxury bath products.
I think his home would mostly smell of wood and florals.
Samphy and Kio's lighthouse: There would be an almost constant aroma of freshly baked pastries, biscuits and cakes, occasionally interrupted by the stench of a botched magical potion.
Jiya's house: Old books, the fireplace and a lingering doggy smell. (She doesn't have any dogs, she's a werewolf). As she's still getting used to her powers, there is occasionally the smell of something else, but she's usually quick to clean it up.
The Strange-Quest household:
Norrell and Leoni's rooms would smell strongly of whatever perfumes/colognes they were wearing that day
Tadeo's room would smell faintly of books and paint.
Rhydia's room would smell probably of laundry and sweaty gym clothes as she likes to work out a lot.
The rest of the house would be relatively neutral, unless Norrell and Leoni have been practising pranks; in which case at least one room would reek of either something rotten, trash, poop or the most noxious farts imaginable (Norrell is especially skillful at not only clearing a room in this manner but also in doing so without anyone being able to trace the smell back to him).
