Early life[]

Gretchin Doublée was the daughter of wealthy parents and grew up in a mansion in London. As a young woman, she fell in love with a young man named Arnold, who worked as a gardener at the Doublée mansion. Gretchin's father disapproved of the relationship and fired Arnold, forbidding him to speak to Gretchin.

Undeterred, Arnold stood outside of the mansion every day, in rain or sunlight, where Gretchin could see him from a window. Gretchin's father was eventually moved by Arnold's faithfulness. One day, after a hurricane had laid waste to the mansion's gardens, Gretchin's father welcomed Arnold back.

Arnold presented Gretchin with a ring engraved with her initials as well as the date of their marriage, "11 22". After the couple were married, Arnold took over the Doublée family's business and travelled the world managing its affairs. He became so busy that he was only able to spend one day each year at home with his wife in London. Gretchin's ring became a precious treasure to her, and she always looked forward to her wedding anniversary, when Arnold would come home. She threw dinner parties in the mansion for those occasions.

At some point Gretchin adopted a pet iguana named Rex, which she doted on in Arnold's absence. She used images and figurines of cats, Rex's least favorite animal, to keep Rex from entering certain parts of the mansion.

Gretchin was a member of "Team Adamas", a group of trusted individuals who were tasked by Lord Maximilian Richmond to look for evidence of precious stones on Richmond's property shortly before his death.
