Back to MyNinjaH8sU's point, what would the in-game mechanical effect of this power be? It sounds freaky and compelling, but determining the effect will go a long way towards building it.
Is the maneuver placing scene Aspects on those locations? Is this a vector for some sort of Mental attack? Is the monster hoping to destroy the house so that it injures or kills the occupants?
If this is just a creepy damage-dealing effect, look at Breath Weapon: it is a generic ranged damage spell, and a benchmark power that many people use as the basis for other effects. The Custom Power thread has some example add-ons people have used for other powers, such as Long Range [-1], or increasing the number of zones affected. You can re-skin the ability so that the targets save using their Endurance instead of their Athletics.
Incite Emotion is another benchmark power which people use to gauge other powers.
