Revan, did I understand correctly that I will essentially be roleplaying Stefania and her daddy separately?
If I directly influence Roderick's decisions and fully take him into roleplay, then Stef will go to Adalard. I wanted to send her first, but I remembered that the 5% bonus applies to all Guildarians + it will clearly be easier for her father to find common ground with Aldelion than with a hated female.
