Vanguard camp near Chadron, Nebraska
The day had slowly worn on to dusk, and Sentry stood in her favorite spot in the camp; a little hill just a short distance from the main body of tents. Her eyes glowed with a soft golden light as she kept watch on the horizon. With her powers she could see farther than any human; even around corners to a limited extent. It was her task to be an early warning system. She could see everything all the way to Chadron in perfect clarity.
The sound of rustling grass caused her to whirl around, her eyes piercing through the lengthening shadows. Sentry scanned the trees but didn't see anything. Satisfied that there wasn't anything awry, she turned around to face the camp only to be met with a knife in her gut. Staggering back and clutching her gut in pain, her neck suddenly jerked violently to the side and she collapsed lifeless to the ground. Shard stood holding the bloodied knife in his hand; his eyes burning like red embers, and a satisfactory smile plastered on his face. He raised his hand to his ear and spoke into his earpiece, "This is Agent Shard. Sentry down. Proceed with the attack."
The first shell impacted without warning.
The earth erupted in violent explosions, as the small caliber artillery rained down, on tents and open field indiscriminately. Men in black tactical gear swarmed over the ridgeline opening fire on anything that moved. The alarm was raised in an instant as mutants swarmed to take up the defense. The founders, Angela, and Cypher rushed out of the main tent and looked on in horror.
Rage twisted Tempest's face as dark clouds formed from seemingly nothing, and a violent gale picked up. Tempest focused his power, and the wind was sufficient enough to blow the artillery off course. Paladin charged to the front lines, his armor glowing in the dark.
"Angela we have to evacuate, we don't stand a chance."
"I know, Cypher, but they need cover."
"I'm on it, just sound the retreat."
Cypher slung on his long coat and drew his guns.
Angela's superpowered voice thundered through the camp, "Flee to Petra!" The code phrase was developed to mean everyone head west, and meet at a special location near the base of the Rockies. Angela looked on as those capable of fighting ran toward the oncoming forces, and the others ran west.
