I was going through the royal palace quests, and now I'm in a room called Royal Memories, and when I try to talk to Nillem he says
"It is an event which proceeds as a memorial. Only the party leader can proceed with a memorial event. Try again after forming a party."
There was no warning that I'd need a party, and I don't know anyone to party up with. Is there a way to move on with this quest, or make a party with just me in it, or something? I don't want to try returning to my save point in case it completely breaks the quest chain, so I'm kind of completely stuck for the moment.
