Calpernia: From Corypheus to the DA 4 Party?

He wanted to rule but it is open to debate whether you consider that enslavement. Solas would, considering that is what he regarded the Evanuris to be guilty of. However, forcing everyone to worship someone as their god is only what Drakon did when he forced people into accepting his version of the Maker by conquest, or the Qun do when they force conquered people to adopt their philosophy. Even the Imperial Chantry use their religion to maintain the status quo that keeps people in power that seem to do nothing to restore the fortunes of Tevinter.

So when Corypheus told Calpernia that he was intending giving Thedas the god it deserved, she can be forgiven for thinking it preferable to the alternatives he intended replacing. She may have felt that they were liberating the mages of the south from their enslavement by the Chantry - it is after all the same view held by Anders and the rebels. Regardless of the time magic manipulation, it was the free choice of the rebel mages to join up with the Venatori. Yes, it was indentured servitude, but that is different to the sort of slavery that Calpernia experienced up in the Tevinter where there was no time limit on it or prospect of freedom after a given amount of time. Remember working to pay for help given is exactly what Hawke was expected to do on reaching Kirkwall, so it is clearly regarded differently in Thedas from slavery, which is illegal in the south.

Calpernia was not the lieutenant of the Templars, that was Samson, whilst Erimond did seem to be running the Grey Warden show on his own, so it is quite possible she did not know what was going on there. We should also remember that everything that occurred in the game was really plan B. Even if not a companion, I'd like to run into Calpernia again simply to get her take on everything connected with Corypheus, particularly what was meant to happen if the explosion at the Conclave had not occurred. Clearly that was totally unexpected by Corypheus.
