So Luna had the only good start?

Well, it looks like her mother is crying so there's probably some kind of sad context here.

The knight seems to be presenting a scabbard, which means the mother might be going into battle. In that context the tears might mean that she knows she won't be coming back.
Could be that the castle is under siege and about to fall.

Well at least this proves that Luna's mom loved her very much. That's good enough for me.
