I decided after Halloween 2020, that I would make an annual special for Halloween and Christmas. These are not canon to any of my stories, though they take place in alternate versions of the universe of some of them. This gives me free rein to do whatever I want. Each part will be a completely independent storyline, even from each other. Like my main stories, these will be uploaded on Archive of Our Own (aka AO3), on DeviantArt, and here on Wattpad.
The Christmas specials will be in two parts. One will release on December 24th, and the other will be released on December 25th. The former day is Christmas Eve, while the latter day is Christmas Day. I'm not actually Christian, it's just that Christianity is the dominant religion in the US, so there are more Christmas specials than specials for other winter holidays at the end of the year.
Since Halloween was part of a three day celebration when it was first created (extending from the eve of November 1st, which is October 31st, which was originally "All Hallow's Eve" before a corruption turned it into "Halloween" to November 1st and November 2nd), the Halloween 2021 Special and Halloween Specials for later years will be in three parts. Each one is a separate and self-contained storyline. They are non-canon to all of my stories, so I can do things I wouldn't in my normal things. So far, instead of going for "spooky" with my Halloween 2021 stories (I know I'm writing them WAY in advance), I seem to be going more for "dark," but even one that brings up genocide has a happy ending. Each one seems to be less dark than the last, though that may change in later years.
