The daughter of Equinox and sister of Brandon Logan Jr - both siblings unaware of their adoptive status and origin in a Hand of Glory ubersoldaten eugenics program. Blessed with a fiery temper and a body in top condition, it seems that Rowena is destined to become the next star agent of the reformed Archer conspiracy. After training with John Done and the Guardians of the Whispering Knife, Rowena was sent to Mark Simmons to continue her education. After a rough start, they established a productive relationship, and it is Mark's attitudes and skills that seem to find the most resonance in Rowena's growth. Much like Mark, she's established a pistol-heavy close quarters fighting style, though she tends to be louder and more stunt-prone than Mark.

Rowena's relationship with her father is strained. On the one hand, ever since she's been away from him, she's gained some perspective on what he's trying to do and respects that; on the other hand, she thinks her father keeps too many secrets - like the identity of her mother.
