Sites that I'm working on at the moment and will, hopefully, be live (or finished) sometime within the current calendar year: gotta get better at this. For things I'm thinking about, keep on eye on my listography!
An overall series tribute for the Old Kingdom series, the universe created by Australian author Garth Nix. There's five books plus a novella to cover, so this'll take some work! My roadmap at the moment is to cover every aspect of the series in detail before moving onto essays of "why this series is so great"... very ambitious, but doable, as I'll ramble about Old Kingdom and how much I love it to anyone who will listen. This site was launched as a work-in-progress for Amassment's Construction Zone: it wasn't finished for the original run, but it's something I'm going to come back to slowly in dribs and drabs. The site in the back of my mind, as it were. (I actually plan to really get to work on it after I finish my ridiculously long prequel fic about Sabriel's parents, but you didn't hear that from me...)
A small list of sites I would like to make and finish in the near future, but as of yet, haven't begun in earnest, or they are not my current priority. They do, however, have notes existing in some form, and perhaps partially written pages or outlines, so the first steps in their development have already been taken... how exciting (daunting. Go work on these sites if you're reading this, Rems).
