They flowed toward him, an endless river of utter evil seeking his death.
“Come!” roared Brox, kicking aside the severed limb of another demon foolish enough to get within reach of his
ax. He stood atop a mound of dead flesh, his many kills. The orc’s body was awash in his own blood, but a strength
such as he had not felt in years filled the graying warrior.
A chaotic fury surrounded the lone guardian, the madness of the realm of the Burning Legion. There seemed no
ground, no sky, only an insane swirl of fiery colors and untamed energies. Had he not been so completely focused
upon his adversaries, the orc suspected that he surely would have been driven insane by now.
Behind him, the portal burned with evil purpose. The green flames danced as if demons themselves and seemed to
draw the Burning Legion like the proverbial moth. Brox had expected that he would be overcome immediately, but
not only had he so far survived, he had kept not even a single demon from reaching the gateway.

This was inspired both by Optimus Prime's epic line in Revenge of the Fallen, and by Broxigar's pure awesomeness.
