>>30583172From what I remember, you're never forced to head to any of he Trial Captain's homes and (with the exception of Lana) all of their homes are accessible BEFORE your trial. As in, if you'd take the time to EXPLORE your surroundings the first time you're in a town, you'd be able to find find their homes. You explore first, and come back after key events to get an event.
In the case of Lana, her home is in Konikoni so you actually can't even go there until after her trial anyways, so there's literally no backtracking at all for her.
