This is just my main fursona, so allow me to introduce myself:

Hello, nice to meet you, I'm "Speepy" but Max is my name.
I'm about a 26-year-old corpse living a pretty standard life occupied by some sort of parasitic thing riding me around like some sort of suit. That's just how it is I guess; not like he's doing anything to hurt me.
You see, when I was 16 running track in high school I tripped and scuffed my ankle on a rock. I have to guess that's when that happened because that wound closed far better than anyone could have guessed. And then my fur started turnin' white. And my horns and hooves started turnin' black. And my chest started to open up... Well, in that aspect I can spare you the gory details. Wouldn't want to make this not safe for the kids, ey?
But that leaves me where I am today... and not much really got screwed up after that. I went to college, met a couple of friends, even met a couple of folks in the same situation as me.
Guess it's not so bad to lose my memory every now and then. No clue what that worm does in the meantime. Wouldn;t even want to hazard a guess.
