Exactly How Many times Prisma has gotten Officially Knocked Up is sorta Pseudo-Canon.
but when Prisma does go All The Way with it, due to her abstract nature and connection to the void, she doesn't actually reproduce in the same way most beings do.
she'll spend an indeterminate amount of time being pregnant, and then a fully formed being will just sorta Materialize itself out in The Space Between Spaces, paradoxically existing as if they had always been around.
Prisma might not even have any idea of the exact presence of her offspring until they meet!
