The Last Great Time War: part II

The Dalek's Worst Nightmare

"Enough of this," the Warrior said. He had been fighting this battle for several years, but nothing worked. Trying to establish a bridgehead on the main Dalek command station had not worked. Rigging the station to self-destruct had not worked. Planting a bomb on the station had not worked. Raston Warrior Robots had not worked. Leading as many ships as possible in through chinks in the force field to blow up the station from the outside had not worked. Everything he tried had not worked, and he'd tried practically everything. Or almost everything. He still had one more trick left up his sleeve. It was very risky, but if he didn't do it, the Time Lords were going to use the Quantum Disruption Bomb from the Omega Arsenal to turn the whole region into subatomic particles. Including at least a thousand inhabited planets. His plan would likely cause collateral damage, but not on that scale.

"Preda," said the Warrior, "I'm going in. It's time to use my backup plan. You lead the fleets now."

"Aye aye, Captain," she replied. She was the only one who could talk to him like that and get away with it. "Good luck," they said to each other.

Preda watched as the Warrior's TARDIS rocketed through the battle, torching groups of Dalek saucers with its jury-rigged energy cannon that still looked like the lamp on a police box. Soon it was gone, disappeared through a temporary crack in the force field.

Preda spoke to the fleets over the intercom. "The Warrior has a plan for victory, and has left me in charge while he implements it. Fleets 16 through 28, execute maneuver-"
"I think not, impudent young lady," interrupted Commander Partheus. "That joker," he continued, "does not have the authority to appoint you or anyone else in his stead while he runs off with another one of his brilliant ideas to get us all killed. I am the highest ranking officer here, and I will assume command."

"Commander Partheus, you can't-"
Preda started.
"Do not tell me what I can and cannot do. You must obey my authority.
Fleet 1, ready the Quantum Disruption bomb!"

The Warrior positioned his TARDIS above the main Dalek command station. It was shaped like a disk, with bronze towers and spires sprouting from the top and underside. In the center was a main column longer and larger than all the other ones, tipped with a long, pointy spire on each side.
The main station was flanked by three smaller ones of identical design, along with many tens of thousands of saucers.
Five War TARDISes surrounded the Warrior, projecting a shield and cloaking field around his TARDIS. He was going to need it, but not for long.

Inside his TARDIS, the Warrior had a thousand distress cubes. These were small boxes that contained the recorded thoughts and distress messages of Time Lords, and were launched into the time vortex to seek other Time Lords for aid. Basically a telepathic, homing, note in a bottle. Millions had been launched during the War, and precious few were answered. Even if there were the resources to answer them all, many turned out to be traps created by the Daleks and various temporal terrorist groups. The Warrior had collected these and made sure they were genuine.
He opened the TARDIS doors and launched all of them at once. They scattered throughout eternity, sending promises of immense pain and distress at one location. The bait was set.
The Warrior hefted the modified De-Mat gun off of his shoulder and pointed it out the doors. Any minute now...

And there it was. A ripple and bulge in space and time, followed by the most terrifying things that you, dear reader, can imagine. The movie monsters that terrified you as a child and possibly still do, all the creepypasta horrors from the Internet, the shapeless terrors from the depths of your subconscious that you don't dare confront if you want to sleep at night, the monster that might be creeping up right behind you right now, all the ghastly fiends that your mind conjures up when you're scared, alone, and in the dark. All of them were there, rolled together with the worst torments of every other being in creation, rolled together into something indescribably unholy that will forever sear its fell image into and haunt the eyes and minds of anyone who gains even the slightest glimpse of it.

The Warrior's other strategies that didn't involve eldritch abominations had all failed because the Daleks would simply alter the timeline from their position of strength to undo them, no matter how successful they might be in a more conventional battle. They would not, however, be able to undo the arrival of the Nightmare Child, and would not be able to undo any events associated with it.
The Nightmare Child ripped, tore, blasted, oozed, burned, and lashed at the massive Dalek fleet that opened fire on it. It smashed open saucers as if they were soggy lentils, burst open War TARDISes as if they were confetti bags, and pulled them in to its cavernous maw from which there is no return. The main command station strained as the demon latched on to it and started to obliterate its defenses.
The Warrior leveled his homemade superweapon at the monstrosity. It was a De-Mat gun infused with the antimatter power supply of a Stellar Destructor. It would repel the Nightmare Child and blow the Dalek stronghold into oblivion.
Just as he put his finger on the trigger, the Nightmare Child turned, and looked the Warrior right in the eye.
Then, it spoke, with a twisted chorus of all the Warrior's and the Doctor's friends, companions, and family.

"You have already failed, Doctor. You have betrayed your oath. You have betrayed yourself and all you hold dear. Gallifrey will burn, Earth will burn, everything will burn except you and your loved ones."

The Warrior could see the twisted and tortured forms of his family, friends, and companions roiling in agony in the Nightmare Child's face. He saw a vision of the multiverse aflame, trapped in endless torment forever.

"You will suffer every agony possible, and some that are not. You and all those closest to you will live for eternity in pain and terror exquisite. The nightmares will reign until the end of time!"
The Nightmare Child laughed.

And the Warrior laughed back.

He fired the gun into the Dalek command station. The temporal engines within exploded, tearing through the Medusa Cascade like an oversized supernova. Thousands Dalek saucers and hundreds of Time Lord ships approaching to deploy their doomsday weapon were swept along in the inferno and wiped away. The rift narrowed as the force holding open was obliterated. The Nightmare Child screeched like a million nails on a million chalkboards and fled, sealing the rift behind it.

The rift was sealed. The plan had worked. The TARDIS lay crashed on a moon that was shattered by the blast, with her owner lying unconscious inside.
