very skunky question, appreciate you being (a) yourself!
I admit my spectrum of 'caring strongly' about scent doesn't often reach the kind of fun kink levels that many do, but it's definitely a sense that I've given a lot of thought to, symbolically!
Amaryllis - A 'blue and purple' type woman, her scent motifs are floral-bordering-on-herbal, motifs of light sweetness but in a way that feels grounded in 'splendours of nature'. Honey, lavender, vanilla.
Also, just in a practical sense, there's a good chance she's going to have an undertone of faint cannabis stank at all times, an earthy terpene undernote. Or overnote, if she blows it in your face . . .
Rillette - oh, rillette, in her head she likes to keep clean, but she's a busy girl, and 'washing up' is never the first thing on her mind, and due to her activities there's a better chance than not the girl is going to absolutely /reek/. Whether it be fantasy monster viscera or mundane fish or pork blood, girl spends more than half her day, working hard, sweating, getting hands deep in blood and guts and death.
She is everyone's favorite depressed musclefluff blorbo, avatar of transmutation of wet raw flesh into 'meat' useful for life, the faint whiff of the underworld follows her everywhere, poor thing.
