I have a name for the series of fics that all take place in the same universe as the fic Sanctuary that I started ages back. I am starting a new topic for the lot of them. This post will have a regularly updated link list to both AO3 and FFN, or at least I will try to, as well as a basic reading order list. Or you can just find them all in order on the series page on AO3 (https://archiveofourown.org/series/858008).
Enchanted Teen
When Clef said he was going to 'grow-up', Umi wasn't sure what she was expecting, but she definitely hadn't anticipated how attractive he would turn out to be, or the effect it would have on her.

Sanctuary Teen(FFN)/Adult(AO3)
When Clef somewhat accidentally invites Umi to stay at his house for a week, it's the start of changes that happen faster than either of them anticipated. Unfortunately, with the laws still in the way, the consequences of that summer may spiral far out of their control...

If you want to discuss this fic series, feel free to add your thoughts.
I've updated the list to include all the new little fics. I haven't posted all of them over on FFN, but perhaps I will at some point.
I really want to see some of the later fic >DDDDDDDDDDDDDDDDDDDDDDDDDD
