Here is an index of glowfic of which I am aware. If you have a glowfic, let me know and I will add it. It is customary to name glowfics either after a light-themed thing of some kind, an anagram or near-anagram of the authors' names, or a combination of the two if you can swing it.
So far I am pleased to report that I've managed to make all my anagram-names vaguely glowy in some way even though I didn't actually mean to do that when me and Aestrix named pixiethreads XD I earnestly hope this trend continues, because it is delightful.
*edit* And here is a list of all the glowfic authors with named moiety colours:
I appreciate the concept of Refraction is glowfic-related, but it seems importantly thematically different in that it's short stories and not RPs. (I'm disinclined to include even Luminosity in the glowfic sphere).
