It's sad to see you go, Aramis Medici, but you're right when it comes to RL>Games. Not to mention losing your muse is never good and none, at for me, would have wanted you to continue a Game you won't having fun with any more even for the sake of being nice. I never want that to happen to anyone. As for the NPC part, I think it might be best to shelf/allow the characters to fade just in case you ever get the muse back and have more time. It was fun plotting while it lasted and I hope to either to see you return or meet you in another rp some day. 

Good Luck with university, Kentsukan.
