Quartz is a botanist dismissed by Prince Cedric for underperformance, with confiscated plants fueling enduring bitterness. He found renewed purpose maintaining flora at Claude's castle under Aileen Lauren d'Autriche's employ. Later joining her Oberon Company venture, he initially backed childhood friend Luc's pharmaceutical scheme targeting Cedric's markets. Isaac Lombard deemed direct competition unfeasible, prompting Aileen to redirect Quartz toward cosmetics development. His efforts yielded prosperous Oberon-branded pharmaceuticals and beauty lines.

Consistently wearing a large eyepatch over his right eye, Quartz speaks minimally yet exhibits innate kindness. Despite interpersonal difficulties, he demonstrates unwavering dedication to botany. A scholarship graduate alongside Luc, he co-manages a clinic while sustaining Oberon roles. His expertise in plant cultivation and application drives both medical and commercial collaborations with Luc, showcasing versatile botanical proficiency.
