Wait. Missingno. That's... a form of OLDEN, isn't it? The glitch illusion of many forms? Our version caused a lot of trouble, too, but suffice to say it was neutralized and then became able to ascend with the others. And in your world, things didn't resolve so smoothly.

["Smoothly" is an overstatement, maybe. Just ask Evan, who nearly died, or Azure, whose body it stole, or Paul, who saw reality break down around him and also got haunted. But in the end, OLDEN was brought around by a little girl who wanted a friend. It seems not everyone can say the same.]
