A clarification on some of the questions debated in the thread, taken from WoT2:
"Her reading had given her an appreciation for Tevinter's past triumphs and a burning frustration with the ruling nobility's indifference to their homeland's slow decay".
"She saw these Venatori as the key to saving Tevinter, a group dedicated to forging a great future for the Imperium and humanity as a whole."
"Her dreams of revitalizing Tevinter included uplifting the enslaved as true citizens of the Imperium. Calpernia believed in the worth of the people unseen by the powerful, and well remembered her own longing for dignity."
"It is a testament to Calpernia's strength of vision that she remained the Venatori's leader, largely unquestioned and second only to Corypheus, until the end".
"The last of the Venatori are scattered to the winds, and those few who can be found either do not know or are intent on preserving their former leader's secrets."

With the standard caveat that WoT's content is considered in-world information, I will take these statements as canonical.
