A sound cuts through the demonic screeching that, much like demonic screeching, is unlike anything Margaery may have heard before. The modern day equivalent is the crack of electricity as more strange green light enters the scene in the form of a thick arc of green lightning. It slams into the demon looming closest to her, instantly forking away to snap the second. It's probably extremely good luck that Margaery herself is not caught.

There's a laugh. Kind of a cackle. The source is a man, a stranger, dressed in armor—dark leather, silver—with a gauntlet currently charged with that same green light at the centre of its palm, sparking crackles of electricity leaping around it.

One of the demons spins around to the source of that laughter, its spider limbs twitching from the onslaught, sliding on over with a scream. Tony, for his part, wheels backwards, gauntlet aimed, seeming to draw the monster away from the lady, and glancing up towards the rift splitting the sky.

"We're closing her up!" he yells, ostensibly to more of those voices Margaery can hear through the trees.
