Sister Argenta is like if Yrliet had been born a human
>Dogmatic with respect to the standard beliefs of her people
>Not very bright
>Overconfident
>Trusted the wrong person just because they were from the same faction
>Let someone down in her past and has survivor's guilt
>Wants you to find something related to that past shame that will help her put right what she did wrong
Imagine Argenta somehow on a corsair ship trying to get the captain to help her look for the One Star. She'd act exactly like Yrliet
