At the centre of any great religion it is not uncommon to find one such entity. These beings worshiped for their power grant their blessings to those around them, sharing only with those upon whom they resonate in mind and soul.
While these beings of pure energy can be said to be mindless and without thought of their own, there is no doubt that some force even greater than their own drives them; the will of god as any devout believer will claim. But perhaps it is the will of a far more primal force that drives them.
As their power only spreads to those who share a like-minded will; they naturally draw in those who share the same ideology as the primal force their strength originates. And in turn, those who's ideals clash with these beings will find themselves eradicated without mercy.
