The Harridans had already killed 6 marines in less than a minute of arriving, and Sefran was getting worried for his men. He was still running with his brother terminators towards the Harridan. As they charged, Sefran and the terminator sergant slashed their weapons at the gargoyles all around them. One of the Harridans which was higher up, spotted the black death bringers and their charge, and began to dive steeply towards them. It fired off a barrage of venom from what appeared to be one of its left arms, and it went hurtling towards the veteran marines. Fortunately, the tactical dreadnought armour of the terminators withstood the barrage and Sefran's religious, ancient armour just ignored it like tiny swamp flied, buzzing around it. However, although its venom had not done damage, the Harridan continued to dive towards them. Sefran knew that they would be overpowered if they had to fight two of them in close quarters.

"Tactical Squad Ablam, on me and cover us!," Sefran ordered. The ten strong squad consolidated together and quickly caught up with Sefran. "Give us some covering fire on that flyer, blow it out the sky with bolts!" Sefran calmly said to the squad.

They opened up and fired their bolts at it. Twenty self-propelled miniature missiles sped towards the Harridan at high velocity. As the bolts hit it's heavy armoured hide, they exploded taking chunks of the beast out here and there, but it did not slow it's decent, it mearly shook itself and continued diving. This is where the holy light of a lascannon would be an invaluable tool of war. Squad Ablam continued to fire, taking more and more chunks out of it, but the Harridan was far to tough for standard bolts. Suddenly, the two heavy bolter emplacements started firing again and a stream of high velocity hellfire bolts ripped through the Harridan, scourching it from the inside all the while. The beast let out a a tremendous screech of pain that would've almost certainly deafened a guardsman at this range, but the marines' helmets instantly compensated for the it and reduced it to tolerable levels. Even though the Harridan was in immensive pain, it wasn't down for the count yet. Sensing it may not be able to contine it's fight, the Harridan let off as much venom as it's body could muster. It fired one shot of the venom at the heavy bolter emplacements. The fortifications withstood the attack, but the bolter postioned there got hit by the venom also and instantly started corode. Another shot of venom found it's target on Brother-Terminator Stade. His armour was still in a weakened state, and the spirit enslaved to it knew this also, so to protect itself from torture in the warp, it threw up an energy field around Stade and stopped the venom mid flight. The diving Harridan had slowed now as its wings were punctured and it was loosing vital fluids, but regardless of that, it was close now to Sefran and his squad. While still running, Sefran, with his powerful exoskeleton pumped energy into his legs and he launched himself head on towards the Harridan. With halberd raised and pistol holstered, he slammed his power weapon straight through it's head an as he landed on it's head, Sefran ran along its back while dragging his halberd along, cutting its spine and wing connections clean in half.

As it crashed to the ground, it snapped it's jaws and swiped it's claws at the terminators, but they skillfully dodged it's dying attempts. To finish it off, Sefran plunged his halberd into it's back and cut away a small hole. He dropped his weapon and coked his pistol and slammed his combi-flamer into the hole and pulled the trigger. It's entire insides was engulfed in flame, and before it could even screech, it's whole brain was fried. Pulling his pistol back out, he holstered it, picked up his halberd and continued his charge towards the grounded Harridan with the terminators. The marines around it were dodging it as much as they could whole firing bolts and slashing blades at the gargoyles, knowing all the while they must hold out until their ferocious leader arrived and distributed the coup de grace upon the second Harridan. Squad Rideal was working in close quarters together, ripping through countless gargoyles as they swarmed towards them. Peno could see his friend's charge and could also see the difficulty they were having moving through the dunes with so many 'nids around them. To save getting split up from his squad, he ordered all nine men in his squad to engage their jump jets and fly in a diagnol direction and hover just above Sefran and give them a good clear path.
