She's an Undine from Orange Planet working toward her Prima certification—basically the top rank in her field. Most of her job involves operating special traghetto gondolas, which is honest work, but it's also a stepping stone to something bigger that she keeps reaching for and falling short of.
People who know her would describe her as quiet and kind of reserved. The thing is, she's been taking the Prima exams repeatedly, and she keeps failing them. That's worn on her over time. Fans have noted she tends to slip into depressive episodes between attempts, which makes sense given how much she's put into these exams. It's a cycle that defines a lot of her character—the quiet determination mixed with real frustration and disappointment.
