Pleasant smells would have faded long ago. The salts used in preservation would have eliminated all biological odors, so you’d just have the smell of dust from molecules breaking down naturally over time as well as mold eventually, since everything old that isn’t metal will mold if not cared for properly. Maybe some oxidization as the bronze and copper they are carrying starts to rust.
But given they are magic, with limber muscles and working organs? I suppose linen. Maybe they’d freshen themselves up with the things they’d be embalmed with, so plenty of good Middle Eastern and Mediterranean smells, pitch and resin, honey, flowers and plant oils, some polishing oil for the jewelry and weapons, and so on.
The reason I’m being vague is because the vagina, urethra, and anus were sealed during preservation and the connective canals may have been severed or removed. So her vagina would be like a stitched Barbie doll, and if opened would likely just lead into her entire abdomen.
