Ich nehm mal an Du meinst den Artikel oder?
There appears to be a few dialog options under "I'd like to discuss something you mentioned" that only show up if you have Sten in your party when visiting certain locations. Of note two in the Circle Tower, both of which don't open a dialog and he says it while exploring. When entering the tower, Sten will say something about how the Tower is unlike the "prison" the Qunari keep their mages in. You can later ask him about mages in his homeland. Later in the library, Sten will make a comment about the people failing to hold onto their knowledge. You can later ask him about this which leads into a conversation about his people and the pursuit of wisdom. Two further dialogue triggers are outside Redcliffe Chantry, where he makes a comment about The Chantry and wisdom (though may be the same dialogue as the Circle library mentioned above), and a party conversation with Zevran regarding qunari in Antiva, which triggers a chain of dialogue regarding the Tal'Vashoth, qunari who have left the Qun. All of these chains have the potential for substantially increasing Sten's approval. There is also one instance where, in Denerim, Sten comments on the playing children, near the Market, claiming they need to be sent back to the priests for training.
Die im Circle Tower hab ich nicht getriggert bekommen, vielleicht funktioniert das nur wenn man ihn während der Quest in der aktiven Gruppe hat. *shrug* Die in Redcliffe hab ich interessanterweise aber auch nicht bekommen, obwohl ich ihn zu der Zeit in meiner Gruppe hatte.
