Ash was in the Unseelie Court in 2012 when Drusilla Blackthorn accidentally touched the Rosales family heirloom and was sucked into Faerieland. She was transported just outside Ash's room and stumbled in, surprising Ash. The sight of the stranger made him wary, and he reached for his dagger and demanded that she identify herself, asking if she was a Shadowhunter. When Dru called him out for being rude, he told her his name but continued to interrogate her, immediately asking if she had been sent by his mother and if she was worried about him. Their conversation was cut short when Dru was pulled back to the mortal realm.
Ash has short white-blond hair, green eyes, and a sharp face. He looks to be around thirteen years old. He wears rich clothes made of silk and velvet and heavy leather boots. He also wears a metal band on his head.
