Good guesses! But I'm a knight of breath tho.
Knight class has a lot of debate over whether it's passive or active and who it's relaly paired with but from what I understand, these 3 things determine the knight's relationship with their aspect.
-The knight uses their aspect as a persona to defend themself
-The session lacks the knight's aspect
-Thus, the knight has to give the aspect themself.
I tried to describe these lol
