If the Titans are the Pantheon of Order, why were they born in the Great Dark Beyond instead of on the Plane of Order/arcane?
One explanation would be that just as the Old Gods were flung out of the Void like spermatozoa, the World Souls are "sparks" of arcane energy that were flung out of the Arcane Plane.
But the titans are supposed to be the Pantheon -- comparable to the Void Lords, not the Old Gods.
