Ash is described as tall and slender, with tousled brown hair and a strong jaw. His mouth curves a bit a the corners almost like he is holding back a smile. His eyes are described as a soft greenish-grey color.
Ash grew up in the Smoke with his mother, father, brothers, and sister Cinder.
When Ash was 15 years old, his sister grew very ill from black lung due to the pollution in the air. Ash skipped school to take her to the free clinic. It was there that Madame Curio found him and told him she could give him a job to earn money to help his sister and family. This job came at a price, Ash could never see his family ever again. He accepted the job and hasn't seen his family in years.
Over the course of the next three years, Ash has been the companion to many young ladies and the property of their mothers. Companions are not allowed to engage in sexual activity with the ladies, but many are forced to sleep with the mothers of these ladies by their command.
Ash was later hired by the Duchess of the Lake to be a companion to Carnelian.
He meets Violet Lasting at the palace of the Duchess of the Lake when he is hired to be a companion for the Duchess's niece, Carnelian. They encounter each other when Violet is retreating from the other ladies-in-waiting, Ash mistakes Violet as Carnelian and they begin to chat animatedly for a few minutes before Violet mentions that she is from the Marsh. Ash realizes with horror that she is the surrogate for the House of the Lake and urges her to hide when Carnelian comes in.
Although they try to avoid each other and pretend not to know one another, they soon fall in love. Since their love is forbidden, they steal small moments together when Ash is not performing his duties. However, their romance leads to Ash's downfall when they are caught together (undressed) by the Duchess. Ash is thrown into the dungeon, leaving Violet on her own.
That night, Garnet of the House of the Lake, the Duchess’ son, helps the two escape. They find Raven and Lucien, then travel to the White Rose, a house in the middle of a magical forest. Ash and Violet once more make love, but are interrupted by Lucien and Garnet. Lucien makes it clear that he didn’t want Ash touching Violet again, while Garnet assures then that he wouldn’t tell if they wanted some privacy. Violet ends up leaving, though, to check on Raven.
He hates avocados because of they're slimy and taste like soap.
