Threia works as a historian at The Center, where she's known Marion Quinn casually over time. Her real passion is studying ruins and piecing together what life was like in the previous era—a specialty that keeps her constantly in the field despite her employer's preferences.
She comes across as relatively composed on the surface, but there's an edge to her. Marion has called her "troublesome," and even Escha found her "a little bit scary" after their first meeting. The truth is Threia just doesn't care much for people. She treats socializing as a hassle and mostly keeps to herself.
Her research has given her some amateur knowledge of alchemy, but she's not a practitioner and can't actually synthesize anything. That said, she refuses to spend all her time analyzing reports from the lab. She'd rather get her hands dirty in the field, risks be damned. When she's absorbed in a project, she tends to forget about things like sleep, food, and housework—bad enough that it sometimes forces her to take time off work.
There's baggage in her family history: her uncle is wanted for serious crimes, including attacks on alchemy institutions. By association, her whole family carries the stigma. When the subject comes up, Threia insists she knows nothing about him and makes it clear she has no admiration for him either.
She and Reyfer Luckberry don't get along.
