Gemma

Gemma is a seemingly emotionless woman somewhere in her twenties who lives on the remote island of Tìr Aonach. She came to the island as a teenager with no name and very few memories, and soon became a servant to the resident dragon, Wrilnora. Since then her day-to-day life has primarily revolved around eking out a living in between maintaining her mistress's horde of treasures. Since the locals find her creepy and since Gemma has little desire for companionship, she primarily keeps to herself and rarely leaves Wrilnora's caverns.

In terms of overall vibes, think Anthy Himemiya meets Cimorene of Linderwall.

She can use magic but is generally less of a fighter and more of an errand runner.
