- “We're all here because we wanted refuge from the divisions of the world outside. We're all looking for a cause that won't fail us, and comrades we can trust.”
In 9:41 Dragon, Reimas follows Knight-Lieutenant Diguier from Orlais and six other Templars to join the Grey Wardens in order to avoid participating in the Mage-Templar War. After finding two inexplicably deserted Warden holds in Orlais, the Templars decide to travel to Weisshaupt Fortress in the Anderfels. Two templars don't survive the journey and another deserts along the way, but Reimas, Diguier and the other Templars reach Weisshaupt and pledge themselves to the Wardens.
Along with the apostate mages and the other former Templars, Reimas finds herself stuck at Weisshaupt awaiting her Joining. One day, while she was visiting the library, she decides to strike up a conversation with Valya. She tells Valya her father's history and her reasons for becoming a Templar, but Valya remains largely dismissive.
While her fellow former Templars become more reclusive after Knight-Lieutenant Diguier dies during his joining, Reimas manages to eventually build a rapport with Valya and the two make a daily ritual of having tea in the gardens. Reimas confesses her belief to Valya that the Templar Order has forgotten its purpose but that she remains hopeful that it could be put on the right path.
Eventually, Valya approaches Reimas and asks her if she has ever faced a blood mage. Reimas admits that she has and that while she was a templar she would have had a duty to strike down any "maleficarum". Valya reveals that the Wardens have previously used blood magic against the Darkspawn and asks Reimas whether it's possible to pursue a noble goal with blood magic. Reimas replies that now she was sworn to the Wardens, she possesses the luxury of being able to see "shades of grey" in such matters.
Reimas along with Caronel and a former apprentice mage from the Hossberg Circle of Magi, Sekah, are persuaded by Valya to join her on a mysterious mission to the Red Bride's Grave. Valya reveals that the Griffons died out after being subjected to a modified Joining ritual that left them all tainted, and that Warden Isseya sealed away a large clutch of untainted griffon eggs in the Red Bride's Grave.After a grueling battle against skeletons, shades and an ash wraith, which costs Sekah his life, the group succeeds in recovering the griffon eggs. After seeing the eggs hatch, Reimas inquires incredulously what they should do with the newborn griffons. Valya replies that they take them home.
- After arriving at Weisshaupt Fortress, Reimas paints over the burning blade of mercy icon on her shield with a simple chevron of blue and grey — the Grey Wardens colours.
