[X] Naga's Tear. This district is the home of the less fortunate. It's also one you're passably familiar with, since it's here Libra established his shrine, leaving behind the glamorous temple in Castletown. With luck, your familiarity with the place and the people living here might be of help.
[X] Castletown. In the shadow of the royal palace, Ylisse's most wealthy live here.

[X] Attempt to talk with one of the Dukes.
-[X] Duchess Arnelle: You understand, but you also don't. Peace, under most circumstances, would be preferable. In fact you would still rather have peace than the war you're currently dealing with. However Plegia instigated this war for a reason, and the one they've given is the desire for the complete destruction of Ylisse and its people. What could Ylisse possibly offer in exchange for peace? Would you even be willing to accept the price they might ask?
