Stargate was my first majorly active fandom - and quite possibly will be my last. I have over fifty stories, long and short, drama, vignette, action-adventure, mystery, missing scene, episode epilogue, and one or two romances.
Angel is the fandom I really moved into when Stargate lost its shine. And that was only because I'd just seen Season 4 and fell in love with Faith in spite of seeing her in Buffy Seasons 3 and 4 and Angel Season 1. Other than ficathon entries, my stories in Angel fandom are focused on Faith.
In Harry Potter, I write either Trio or Marauders. Mostly Trio, I think. I don't write romances, I tend to write stories about the trio interacting with each other: drama, I guess it would be called. They all are exceedingly fond of each other, but there isn't much explicit UST happening. When it does, it's usually R/Hr.
I used to write in X-Men comicverse years ago. Most of these stories have since been taken down. However, recently, I have become interested in writing some things for the movieverse. If so, my focus will be Scott Summers and Jean Grey.
