As a youth working on her father's farm, Cauthrien became aware of a man being chased by bandits. After helping him fight them off, she found out that he was Loghain Mac Tir, the hero of Ferelden's war with Orlais. Cauthrien volunteered her service to Loghain, working her way up through the ranks with hard work and determination to become his lieutenant, a position in which she takes great pride.
- [To the troops at Ostagar] Pull out! All of you, let's move!
- You are very bold or very stupid to threaten the teyrn before witnesses. [to a Human Noble Warden who threatens Howe when meeting him and Loghain]
- Don't interrupt, churl. Your betters are talking. [to an Elven Warden challenging Howe]
- Bring them down! Loghain wants the Warden, dead or alive!
- Courtesy of the Survival skill, Ser Cauthrien is listed as an Elite Boss in the first encounter during the Rescue the Queen quest. If she isn't slain while trying to arrest the Warden, she will attempt to stop the party from entering the Landsmeet, but this time she will be listed as a Boss.
- At the Battle of Ostagar, when Loghain orders her to sound the retreat, she is seen with both a two-handed greatsword and a shield on her back.
- During the last scene in the battle of Ostagar, when Loghain tells her to order the men to retreat, she is seen with a shield, but also has a two handed sword, instead of a one handed one. This was likely a large slip up as all of the solders behind her with shields have two handed swords as well.
- If you kill Ser Cauthrien, recruit Loghain, and sacrifice yourself to kill the Archdemon, she still shows up to your funeral.
- It is possible to get two of The Summer Sword if you manage to defeat and loot Cauthrien before being taken prisoner by the remaining guards in Arl of Denerim's Estate, she will reappear before the Landsmeet.
- If you kill her in the Rescue The Queen quest but still fall to the Guards accompanying her she will still try to prevent you from entering the Landsmeet. This is easily explainable in most cases, as she may have just regained consciousness, but in certain kill animations you may remove her head!
- If you try to persuade Ser Cauthrien not to fight you before the Landsmeet, your success will depend on your poison making skill, not on coercion.
- If you allow yourself to be captured by Ser Cauthrien, if you return to the estate (For example, to complete the Correspondence Interruptus Quest) Then Ser Cauthrien, her knights and mage will sometimes still be in the room along with Anora and Erlina but they will not try to fight you.
