The vessel's outer hull was in ruin, a scar of melted metal spiraling across the ship. The captain with his own eye sees their attacker, a measly five small attack craft easily out maneuver constant shell fire while itself release a combined torrent of lighting wearing havoc across the heavy cruiser.

The inhuman pressure suddenly disappeared, making the whole commander deck less tense.

'The bastard is finding his way to the drop pod, abandoning ship I see.'

Even though the moment looks extremely grim the whole of the command deck is hard at work preparing for the next attack wave, each member shouting orders to their assigned sector, issuing orders to the slave the servitor and the still living to maned the gun, the light, telling them to fix whatever they can and to brace for the next wave. Most do as their told, following their master's order and swiftly go to work, voices filled with dredge were heard from the intercom.

The whole crew unable to accept their fate was hard at work repairing the ship, some of the newer members trying to approach the drop pod only to have their entire body bisected, for those are only for their lord to use. The bisected corpse was discarded to the side, trampled on by the hordes of busy crew members trying to live, trying to fix whatever they can.

The captain noticed a few blinking lights in the nearby terminal indicating that all of the dozen of drop pods have been released, he also witnessed a dozen or so more being released from the damaged cruiser beside them.

There was no relief in his mind knowing that his master have escaped from this doomed battle, he's not the nobleman of the imperium who will gladly give away his life and the millions live of his subordinates just to aid the space marine in their conquest. He treasures the lives of his crew members more than any other, even those selfish space marines if they were still here fighting with him. And now being abandoned by them the captain releases a curse on his cowardly lord, even though those word of him is meaningless for he is not a psyker capable of bringing down a curse upon the space marine.

The only thing that the captain is remotely thankful for his fleeing lord is the atmosphere created by their escaping, there is no more inhuman pressure looming over their shoulder, no more criticism of imperfection, and for the first time in a very long while he can unbutton his pant loosen up his belt and let out his belly. Stress eating have been haunting him the moment he made the captain of the vessel, it not long after that a noticeable fat cap appear on his body, he tried to hide it with a tight belt in fear of his lord noticing and cruelty ripping it off him.

Hearing a footstep come closer, the captain looks up from his terminal and sees his first mate who also loosens up his belt, he is now more calm and collected despite the situation at hand.

"Captain their no sign of another attack, their attack craft have also retreated."

"Ready for boarding action, all personal ready melee weapon."

With the attack pattern of this enemy, there is no one location to focus defense on so to be sure the captain orders all personnel to be armed and guards ready to be dispatched in the area where the fighting appears.

Satisfied with the crew response, most have been armed with melee weapons and the specialized unit have been assembled and ready to dispatch, the captain turned to his first mate.

Only for said first mate to take hold of the captain's head, his nail digs deep into the captain's skull holding him in place, the captain hesitantly reaches for his pistol bolter. And before he could take the shoot to kill this betrayer, the first mate mauled the captain's face with his mouth, ripping off the captain's left optical sensor and killing him slowly and painfully.

The last thing the captain see is his crewmates in the command deck killing each other ripping themselves limb from limb. He curses his lord with all of his heart before succumbing to his wound.

'To use warp sorcery on their crew mind just before running with their tail between their leg how cowardly can one being be.'

The necron cruiser slowly approaches the three still ships, and after confirming that they are not being shot at when within visual range, the cruiser quickly approaches their defenseless enemy ready to teleport inside to harvest the technology their master wanted.

In the mid of the pandemonium, several necron boarding parties teleported to the inside of the chaos vessel. With their inhuman strength, they make quick work of the surviving crew members, their enemy crudely made melee weapon harmlessly bounce off their necrodermis bodies. The robotic skeletal hand of the necron warrior easily crush the skull of these frenzy human, their axe head bayonet cleaves away the wave of the incoming enemy. Gauss beam traveled across the tight ship hull, atomizing any living being or dead corpse in front of it. They advance with singular purpose, guided by instruction of their ship many sensors and scanners seeing through all of the many halls and dead end of this vessel.

The necron kills its way to the designated location ignoring the lass gun firing at them, quietly shootings their gauss flyer with deathly precision. After reaching the main engine, the warp drive, and the gellar field generator, the necron use their own bodies' unique signals to mark the location of these engines. After finishing the marking process a huge chunk of space is craved out of existence containing these engines, it then be put at the designated area in the planet below to be researched.

At the same time as the retrieval of the engines, a swarm of scarab invaded the ship command deck, library section, the mechanicum section, and anywhere within the ship that contain information. Eating it along with the ship to transfer said information, converting materials, and building more necron construct.

Feeling fulfilled with the result of his first operation after a long while demiurge separated from the throne, disconnected from the sector, and stop his control of the battle leaving the clean up for the drone.

The battle planning was crude and rough, matching the presumed strength of their enemy is quite difficult for the newly awakened Nazaric, the cruiser he sent to battle is bearly operational to the point of needing Demiurge to manually fine-tune it just for this mission. No doubt that after this mission he would have to focus on the restoration of the tomb world and the fleet as the foremost priority. Their foe is barbaric and slow but their tenancy is worrying, to launch their most deathly force to attack the enemy base just before having their ship destroyed makes demiurge admire their zeal. Their zealotry is commendable but still too weak to withstand the psychic force of the sepulchre weapon system. And much like their mind, their attack crafts is as much as delicate.

'weak will or just in un-evolved, unlike the aeldary the psychic wave scrambles their brain completely. '

The retaliation attack crafts neutralize with just a burst of energy. To destroy the incoming wave of attack so easily give Demiurge an idea of the human defense, strong against physical blunt damage but weak against energy attack.

'upon further review, my attack force might be a bit overkill but the supreme one victory against an unknown enemy must be secured. Especially when this is our first fight upon waking up. To fail the last supreme being expectation is unacceptable.'

Demiurge makes his way to the throne sector, excitement fills his strides eager to receive the praise of his lord.
