Of course, it's all personal, but it might be of some use to others.
"How important" might not be related just to friendship or love, if an arch nemesis got hold of your character, tortured and killed them, I'd say that also counts as important.
For effects, it could be to avoid the area for far longer than just the prescribed 24 hours, fear the character, change something in your own character's outlook, or a thousand other things. Playing impact is fun. Letting others have an effect on your character is also fun, I think.
"Well played" is a loose definition, I define it by use of punctuation, number of words, and emotional involvement in IC and not in OOC.
