Seteth wasn't happy about you being made a professor at the Officer's Academy, and he wasn't going to pretend he was. "I must speak plainly. I am against intrusting such a responsibility to someone like you, but it is as the Archbishop desires. Lady Rhea has requested that I show you around Garreg Mach and help you familiarise yourself with your new home. Come, there is no time to waste." Seteth starts walking towards the Officer's Academy, expecting you to follow behind him.
