I read Homestuck, but I would not say that I meaningfully Homestuck. I find some of the lore vaguely intriguing and think a lot of the characterization is spot on, but also it does this thing where it goes EVEN MORE EXTREME all the time. Which sort of makes me quirk an eyebrow and go, "Good for you, dear, now sit down before you break your setting."
Anyway, 413 isn't purposefully a reference to Homestuck, it was the first number that came to mind when I was figuring out year length. Subliminal Homestuck? You decide.
