I have supped full with horror.

[wand_wavers]

For a moment, the briefest of moments, Hogwarts is silent. It's the silence of surprise, of blank shock; even as deep below the castle, a wizard perhaps more powerful than any other in the building raised his hands and prepared to fell them, Voldemort's Inferi crumpled lifeless to the ground, every one. No wizard did that - nor any magic worked by an Old One - and for a moment, the briefest of moments, the fighting stutters to a halt as the combatants stare at the fallen bodies.

The silence of surprise, of blank shock, and - as something tenses in the air - the silence of a great, indrawn breath.

And then -

The explosion is bigger than it should be, bigger than it was ever supposed to be, and only in the furthest, deepest places of the castle will it not be heard.
