The mission objectives are twofold, as laid out by the expedition leader: Set. Objective one is the retrieval of a rare medicinal herb for interested parties. Objective two is to reach a temple in the far north, as it's allegedly of some importance to Set.

[The latter was more of a personal objective, but Byleth didn't care. He was being paid whether they were out to pick flowers or to go hunting for some long lost temple.]

So, I'll have plenty of opportunities to come across interesting items of possible worth.
