A long time ago, a large group of people were added to Crimishia's head, and it was chaotic. But then Almerissa stepped forward and put up a wall in Crimishia's head, put in a big sturdy and closed/locked door in the wall, and made sure that most of the people were on the other side of said wall. This is how the two of them believe they met, although it's incompatible with the Encryption Algorithm theory. The back room is still there, and so is the Door. Occasionally we've had need to let the wall down, or open the door, and some strange things have happened. Most of the time we keep the wall and door in place. We once thought that there were a thousand people behind that door. I don't know how many there are but it might have seemed that way at various points.
