Sounds good.

The bogle only spawns if the target's fear can be represented by a tangible entity. Being afraid of a concept doesn't count, so the Magna Pater is summoned. The Magna Pater of course is called by the spell because it stands at the top of the fear echelon. The only reason it doesn't pop up all the time is because few have ever met it and come away capable of telling stories.
